You are too kind. That would be kind'a cool 😄 Buuuut as I point out in the video, the idea existed before. I just translated it to Octane 😇 Thank you for your great comment. Made my Day 🙏
Hey hey and thank you very much for your comment. Fantastic to hear you like it and your compliment 🙌 That would be nice if something as a C4D hall of fame even exists 🤔
Thank you. Yeah, doing my best to bring you new and exciting stuff. As it´s always the case with creativity and development. Not every tutorial is as innovative and "brilliant" as this one. But every once in a while i get there 😄 😇
Ohhh, thank you so much. Makes me happy you say that. I was having really bad headaches while recording. So recording was very slow and I needed to record a lot of takes for every single step. Recording went on for 10h 😇 But reading your comment, I think the inconveniences paid off 🙏🙌🫧
Never thought that one could easily switch the meshes to volumes in th object tag! That could also be extremely useful for rendering fluid bodies with non uniform density, like swamp water, tanks filled with mysterious substances and so much more! Thank you!
Thank you for your comment. I like the way you think. Yes, those are some really interesting ideas. I like those! You could possibly also color your volume through a noise or gradient 🙌
Thank you very much. Yeah it's one where most people are surprised that something like this is possible. But as I also say in the Video. This is not my idea. Blender did it first 🥳
Thank you very much for your comment and your kind words. Every once in a while I find out stuff like this. In the mean time I do lower profile tuts. I hope you still like those 😇
Thank you very much for your comment Lucas! Great to hear you find it useful. Yeah I was a bit skeptical if the technique would even work. But it brought better results then I initially hoped for. So I knew I had something special on my hands for this week 😄 Thank you so much for the ✨🫧✨
Love when I watch your vids I pick up so many tips. Like I could never really think of a reason to use the compare node, but now I know it’s actually the answer to the issue I’ve had with the add node all along! 👌
Hey hey and thank you very much for your comment. Fantastic to hear that you found some bits that you could learn from! It´s always a joy to hear that the videos are well received 🙌✨
Perfect! Some months ago I tried to make a foam for a shampoo bottle and I was failed. So it means I will go back to this project again) Thanks a lot!!
Thank you very much for your comment. Let me know if you get anywhere. I tried to make it work in RS to. But only managed to go the route with the volume builder that is voxel based and therefore very resource intensive. If you find a way to use Shaders in RS volumes directly (not translated via voxels), let me know!
A few months ago I spent many days building a very similar solution for a client project. It worked but ended up being hackier than this solution. Wish I had this back then. Thanks!
Thank you very much. Yeah I know those situations. Actually I was in the same situation before where I just built foam from displacement maps. I had this in mind back then but was not able to get there because the last component, a volume shader that allows density through textures, was missing. Luckily we are here now and whenever I have a request for foam again, I know a good way now. Well it has its limitations too... but it looks convincing as a still at least🙌
@@SilverwingVFX Yeah, definitely more convincing than anything you could do with displacement. I went through trying displacement, making complex geo through Houdini and finally ended up with something similar to this in the end after seeing someone made something similar in Blender with Cycles.
🫧 Mind blown!! Love these Quicktips as usual. Was experimenting with making Nebulas in Cycles/Blender. Couldn't work out how to translate to Octane. . . . . I do now though. Thank you 🤗
Thank you very much ✨🫧✨ I love your approach. Not only seeing the tutorial itself but also it´s implication and potential on other stuff 🙌 That´s the spirit 🫧
Thank you very much. Appreciate that you like it! I have made a Blender Octane version too. Heads up. The noises in the volume and the Shader don´t align there. So you have to turn the volume Shader +90° on the X axis for some reason. Or, if you are Patreon member, you can download the Blender Octane scene from there... ✨
@@SilverwingVFXAt first I converted the mesh to a volume from the object menu, but couldn't get the textures to match at all. Finally downloaded your scene file and saw that you had done the mesh conversion through geometry nodes, which worked. I had actually thought of the possibility of doing the entire setup in geometry nodes. Between watching your tutorial and looking at the Blender Octane setup, I finally got the desired result. Thanks once again!
Hey hey, super nice seeing you here Paddi. Great you liked it and you did actually follow 🙌 I see you are getting into 3D artistry ✨ Cheers and an amazing start into this week to you!
Thank you very much. Fantastic to hear you liked it! I think the technique originated from Cycles. This is one of the thing I like better in Cycles over Octane, it´s good integration of volumes. It´s a bit more easy to do that effect in cycles actually as the volume of objects is not voxel based but also lets you use textures in it´s density. I wish I had more time to do all the tuts for C4D Octane, Blender Octane and Blender Cycles. But there is a limit to how many tuts I can record in a week... 😄😇
You keep blessing us with your amazingness! I used to do this with an animated 10k foam texture, but the file size was enormous (dozens of gb) and it was too overkill for my machine. I'll definitely try your method, this looks fun! Thank you so much! 🫧
Thank you very much Sleezy! Yeah I know that there are even animated textures for foam out there that also work quite well in certain scenarios. But not in others. At least my technique is looking decent for the stuff I show it. Definitely has its disadvantages too.... so in the end it´s good to know a couple of methods and just use the one that applies best. And thank you so much for the ✨🫧✨ Yay 🙌
Thank you very much for the praise. I am barely translating an existing concept to Octane 😇 Though I greatly appreciate the huge response this video has caused 🙏 🙌
Thank you very much. Yeah it´s not the first thing you would think of doing. I guess this makes it a but unique 😊 I did not explain the single steps to closely. e.g. what a Voronoi noise is doing. So I hope the audience can pick that up and understand it as is 😇
Thank you very much. Yeah when I first started thinking about it I was sure that It could not be VDBs because it would have been insane ad a huge burden on the scene to put all those details voxels. I am therefore so glad that octane allows you that shader based workflow 🙌
Thank you. It´s more or less an experiment ha ha. Glad you hear you like them! Yeah I think they still miss a bit of a sound effect. Maybe I can get Lucas to make a jingle of some sorts 🤔
Very cool effect Raphael. I had an almost exact same setup back when I used Octane but it was dog slow because back then you couldn't just pipe a C4D Noise into Displacement without passing it through the Baking Texture node. So I had to do everything inside the Volume Builder 💀 while using the same noise for a geometry displacement (Displacer deformer). Because surprise surprise, if you use the same noise and seed inside C4D (like a field or something, using the CPU) and in Octane (on the GPU), you get different results. But your quality is insane, just so damn realistic.
Hey neoqueto, thank you very much for your entertaining message. Yeah. I thought for a longer time how to make it work. And the biggest hurdle was that I could not use VDBs or a voxel based approach because it would be to resource intensive. All those small details in a volume are almost impossible to do on a voxel resolution level. I also tried to make the same shader in Redshift and did not manage to get there. Because I did not find a way to control the shader with a texture and would have to go through the exact workflow you described above! I did not even get to the point where the noise of the surface is defined differently then the one in the volume 😬 Great to hear you like the approach I took 🙌
@@SilverwingVFX I've posted my version of your tut-outcome on the Octane Group (and also on our Stack - 3dsmax group). Since this is a mind blowing tutorial.
🫧🫧🫧 I will for sure build out a scene with this new knowledge! Thank you for always providing actually useful and industry building tuts for the community! I'm also patiently awaiting that BEAUTIFUL Opal shader tut!!! Maybe a 2024 premier?? 🤗🤗🤗
Hey Jerome, thank you very much for your comment and thank you very much for your kind words. Yeah every once in a while I have topics just like this. In the mean time I make more low key tuts that are hopefully helpful as well. I am still on the development with the opal shader. More off then on right now to be honest as I hit some serious walls. I am not sure if I will ever make it work to the standards I have in mind. Would be so cool though having an opal shader that really behaves and looks like the real thing. Maybe, like with the foam shader just now, I have a breakthrough. Fingers crossed for that! Cheers and thank you for your support ✨🫧✨ I really appreciate it!
What a great sharing. Very interesting way to create procedural foam bubbles. Thank you so much. I am trying to follow your idea to recreate in Redshift. However, I have got a problem to match the bubble cut out and displacement. The shading happens after meshing (displacement) so they can't match. Basically, the texture used for displacement is not going to be the same as the vertices have moved. Just wonder why Octane doesn't have the same issue. Thanks in advance.
Hey hey and thank you very much for your comment. I think it will work in RS as well. It might be that the noise is not matching up between the volume and the geo. I remember I had to switch the RS object shader to input source "World" in order to match up with the volume. Not sure if this helps! I guess there is always a slight mismatch between shading and actual volumetric noise because of the displacement / shading order. But it should still work half way decently and look rather good. I have a working RS version on my Patreon if you are interested. It will work in RS 3.6.00 and newer. This is because it has the new RS Standard Volume. Therefore it became possible to control shader density via textures. And therefore finally also create the foam techniques in RS. Though the volume noise can't be moved with the original Object, therefore no animations possible :-(
This is really cool, thanks for sharing Raphael! In real life, wouldn't you also see the specular material refracting inner walls of the bubbles? I wonder if there is a way to create voronoi cell geo from the same noise?
Thank you for your comment. Yes you are absolutely right. Maybe I should have been going a bit more explaining the physics of it... Anyway. In reality you would have the reflection of all of those small bubbles but you would not have a volume. So basically what we did is accumulate all the small reflections that would happen in real world and distributed their energy to be a scattering (volume) instead. Of course there is a difference in real world between scattering and reflection. But the smaller the bubbles are the more those two converge into the same behavior. So for a more realistic shader it would be nice to have the inside of the bubbles also reflecting. Though this is not possible with our shaders as of now since a reflection needs a polygon wall and can not occur from a volume density change. There might be some tricks you could use to sort of get there, but there are vastly complicated and, as far as I can think of, all have drawbacks: I am thinking of creating a parallax occlusion on the surface material as well as some normal direction from the underlying noise to map the reflections of the surface to a depth that is seemingly inside the material with the orientation of the "bubbles" inside. Though you would have to use stochastics to get different reflection layers on top of each other and since all of it is really only simulated on top you won´t get the natural obscuring of energy through the volume between the internal bubbles. This is all well beyond my paygrade and also the reason I am struggling with the opal shader material so much as this is playing with ideas along the same lines. Well, thank you for visiting my ted talk and thank you for reading ha ha ha. Cheers!
@@SilverwingVFXThanks Raphael, always appreciate your ted talks!! Yes it certainly does seem tricky to get that fully in shader, I was imagining maybe tackling it with something similar to the flakes shader in RS (which I think is similar to what you mention with the parallax occlusion / noise / stochastics), but you're right that the volume won't interact properly. I'll let you know if I ever tackle the full geo approach in Houdini someday haha. Best of luck with your Opal shader!
Amazing! But now how do we up the level and make this amazing looking foam slide down the side of the bottle, for example? Let this be a consideration for your next tutorial :)
Thank you very much for your comment! Yeah, that´s the big thing! In other engines such as Arnold or Karma there are so called rest positions that can anchor the noise to a meshes deformation. But this does not exist in Octane yet. I have thought about it a little bit and think this will be rather hard to implement with the available tools. P.s. foam sliding down the bottle linearly will be OK. It´s just not possible, when the mesh deforms 😇
Thank you for your comment. The Shader is anchored to the axis of the object. You would need something like a "reference position" "initial position" like in Arnold. To my knowledge Octane doesn´t have a feature like this, So the noise will always slide through deforming geometry. With alembic it also really depends how it was cached in the host app. If the geometry is non deforming and the axis is moving, then it would work. But if the axis is at the scene origin and the points of the geometry are animated, then it would start sliding. Hope this helps to get a bit of an insight in the matter. Cheers and a great start into this week to you!
Here´s the video I am talking about. ua-cam.com/video/4EZezYWyelM/v-deo.html If you want a Blender Octane version. I have a scene for Blender Octane uploaded on my Patreon 😇
@@SilverwingVFX I followed all steps inside Blender Octane and just can't get the noise to match between the foam object and the surface object. Even though I use the exact same node and projection settings 🤔🤔🤔 I bet i am missing something
@@VaggelisRoubos Thank you very much for your comment. I faced the same problem as you did and It took much more time then I am willing to admit to come up with a working solution. However the working fix is very simple: For some reason the texture space and the volume space do not align. So what you have to do is to rotate the texture space +90° on the X axis.
Thank you for your comment. Make sure you have no transforms in your noise other then scale. Also your object axis need to be on the world origin for the noises to align! Further, if your density is rather weak it can seem that your noise is not aligning because you can look inside the volume quite a bit so what´s going on inside the volume and on the surface can look disjointed. I hope you will get there!
Hey there and thank you very much for your comment. I think you are speaking of the step where you voxelize your object to make it a volume? Maybe you have your Tag on the base object instead of the SDS Object. Or you might have to large voxels and need to make them smaller. Hopefully one of this will work.
@@SilverwingVFX I followed your tutorial tips for placing labels on the SDS, and in the OC render window it shows a rectangle instead of the actual object shape. The parameter settings for the label and object are the same as yours. Thank you very much for your reply!
Woah! this is nothing like i had in mind, Amazing and very eye opening, imagine how more powerful it'll be if we could gave something like pin material, i forecast a flood foamy bear renders for the coming weeks haha, what a trick, in some of my work in product viz, i needed to make a foam shader for a shoe sole and the way i went about it is the usual texture hacks with sss, however i had to change to redshift because with all the displacements in the scene i was constantly at least 4GB out of memory, i was working with a single 2080, fun times (sarcasm) i was messing with projections on the side, i found out all the primitive ones work but also we can't really pin them to the surface of the geo so the best way to go is the XYZ to UVW, also triplaner works* + sticks to the surface and survives the bend deformer test, however, if you're not careful, your foam turns into swiss cheese or a cowboy hat i wonder if there's a way to use geo as a cage to deform it with the surface, something like mesh deformer or FFD, all that aside, i think another solution is if in the future it becomes possible to use the standard volume into the medium input in material nodes, that way we can use the pin material tag to freeze it and use deformers on top thank for unlocking a new part of octane, didn't know that the object tag is this powerful as a shading tool, wish you a great week ahead full of clean 🫧🧼renders
Hey hey. I was waiting for your comment. Thank you again for all your time and effort you pour into those! About deformation: I guess we would need a rest state / pin / initial state for that to work. Right now the noise inside the volume does not even know the objects origin if we don´t explicitly tell it (Through linking the Null). So it´s unfortunately limited to non deforming geo. Depending on the shoes sole I would probably go with an UV map and then with texture displacement. But it really depends how "foamy" the sole looks and how much of the inside you´d see. P.s. does the Pin Material work? I was under the impression that Octane does not have a way to pin materials other then UV maps. Would be really cool if I was wrong here. That would open a lot of other possibilities. So for what it´s worth this should work for non deforming geometry, though I think there also might be problems with motion blur on fast moving e.g. sponges flying through the air, since the volume is only a translated texture. And I don´t think texture translations are supported by octanes motion blur. I stated in a comment before that I really prefer cycles approach here having volumes and objects more connected so you get all the things you get in a texture on the volume too, and you do not have problems moving the object and the volume density noise to move with it. But well, you can´t have it all. There is always a thing that does not work and needs a workaround. I am glad to have gotten so far as this is a very good way to make foam on static- or only slightly deforming geometry. It can get only better from here 🙌 A clean start into this week to you too ✨🫧✨ 😄
haha! of course i enjoy thinking and sharing my experience linked to the topics of your videos 🙌 unfortunately, i can confirm the pin material tag is not working for octane projections, however it works if you'd use the c4d projections on octane materials, even if the object has no UVs for the shoe inner sole it had voronoi like texture, I'll share with you images once i dig through my old files 🙏 yes i remember that comment and it makes me wonder about the algorithmic limitations that causes these compromises and why isn't there a truly complete render engine (besides real life 😂) in existence, but as you said, it only gets better from here 🙌 Cheers 🫧🌟 @@SilverwingVFX
Interesting question 🙌 The only solution I have found as of now is to dock your window. So you do not have the window title showing up. And then you can klick on the hamburger menu and disable "show title". Let me know if you find another way!
Thank you for your feedback. It should not be necessary to use C4D 2024. This should work with all C4D versions that Octane supports. I had a comment earlier from someone who had the same problem. I could not recreate it unfortunately. The only thing I can think of is eventually you have your voxels set to low and therefore your only see one cube. If you find a solution, I would appreciate if you let us know what it was! Cheers and thank you very much!
Thank you very much for your comment. You can re-built it here with the tutorial. It's not that hard actually. But you can also subscribe to my Patreon (lowest tear gives you access to everything) Including this foam shader as well as a lot of other shaders, models and scenes. The link is in the description.
Hi there Silverwing! I got the Cinema 4D 2025 version and in the first steps, I don't have the Volume step length, but rather Volume step percentage. Default being 400%. No matter what put in, my cube is dark grey not white. Even in the Scatter, when I remove "density". What am I missing? Thank you
Hey there and thank you very much for your reply. Octane in 2024.1 changed it's system to teh "Volume Step Percent" You can find out more about it in my newest Video: ua-cam.com/video/_Z1NMHxk9xY/v-deo.html What you need to do as well is set Scattering to pure white, remove the "Density" argument from all the channels except "Density Channel" And set Transparency to full black. That should do the trick!
@@Harrycat Volumes are definitely on the heavy side of compute. Especially with the spectral nature of Octane. It still depends though. If it feels rather heavy and laggy, then I advise for increasing the step percent until you see density changes that you don't want. This can increase performance a lot. Basically what I say in the former comment linked video.
@@SilverwingVFX I did all of the steps but it remains grey, and the range node won't connect, weirdly. I'll downgrade and try. edit: fix for range node is, dragging in range node then you can add an 4dnoise as the value, etc. - still dark grey rather than white sadly. edit: something that fixed the grey was using the emission, mode to density, weight to like 0.7
@@prev Great to hear you sort of got there. What you are doing right now is making the volume a light and therefore avoiding it becoming too dark. As everything is allowed that works at the end, this is a good solution if it works for you. Though of course this is not physically correct as foam is usually not emitting light 😇 I am sure there is a plausible cause for why you are experiencing this darkening 🤔🤔 It might be the density channel that is added to the scattering per default. Other then that, some causes could be: Too high Density (too small value in the Volume Step Percent. 100% should be a good value, but Octane has not been "trustworthy" in it's new version and it strongly depends how you have generated your volume. If it's not a "Mesh To Volume" then the scene size also plays a role how much percent you have to set. The render-kernel is not set to Path Tracing but direct lighting. The Scatter Depth is too small (also note that the Scatter Depth is limited by the Diffuse Depth) I recommend setting both to 8-16 depending on your system resources. The GI Clamp is set to low. It can make Volumes rather dark. Values from 3-10 should work Other then that I am out of ideas for now. I would have to have a look at the scene. I hope one of the above points work for you though 🙌
I think it might have something to do with the Octane version that you are using. It came in around Octane 2022. If you are using a version before that, you do not have the possibility to use "Mesh To Volume"...
Thanks for the quick reply. Yes that is the correct answer, old version; i did found half of a work around using voxels with the volume builder tag but.. still stuck tho. You have a great day!@@SilverwingVFX
Thank you for your comment. I tried that in Redshift. But I could not make it work yet. Possibly because of my limited knowledge there. The only possibility I found there was to use the C4D volume builder and use a texture field with a noise in there. But that makes everything dependent on voxels and not textures alone to control densities. And therefore this approach will be very resource intensive. I will let you know if I find a better way.
hello, i tried follow your tuto to make this amazing foam material, but i working in octane for blender, usialy its not that big difference, so most of materials i can replicate in blender from C4D. But this time i am struggling, cant find the way to make Mesh to volume in blender, its quite more complicated i gess. Can enybody guide me how to mimicking this sheder in Octane for blender? thank in advance
Thank you very much for your comment and your question! The way you would do this in Blender is not via Octane but via Geometry Nodes. There is a Mesh To Volume Preset. I have made a Blender Octane version too. It's available on my patreon. Though you should be able to get there without having that scene. Small heads up. The noises in the volume and the Shader don´t align there. So you have to turn the volume shader noise +90° on the X axis to line up for some reason.
@@dmytrosurin1384 Blender Geometry Nodes. Has nothing to do with Octane. You just need a way to convert a polygon volume into a VDB. IN C4D Octane can do this. In Blender Geometry Nodes can do that. You can access that as a Blender Modifier! Hope this helps 🙌
@@SilverwingVFX I am so sorry I don't understand, I using octane render in blender, not cycles, that's why I looking tutorial for octane in C4D , usually it works, but can't get volume same way like in C4D.
@@dmytrosurin1384 I think I understand you. That does not change my answer. Let me try to explain this: For the tutorial to work you need a volume with the same shape as the mesh that creates the bubbles. It does not matter where the volume is coming from. Whether it's created by Octane or Blender. Octane Blender does not have a "Mesh to Volume" so we need to use Blenders function for it. A Volume is nothing Octane specific. Think of it as an asset, just like a mesh. You can generate it and then use whatever render engine to render it. In your case this is Octane. When you have the volume you can then use Octane Shaders to bring it into the renderer. And if you can't get there, as I said, I have a blender Octane scene for the foam shader on my Patreon 😇
Thank you very much for your comment! I would argue against it. At least technically Octane is doing exactly the same in Blender then in C4D, so there should not be any difference in quality. Maybe it´s the fact that I have much more assets ready for C4D then for Blender, as I have been using C4D for a lot longer time now 🤔 Cheers and thank you for your comment. I respect your vie of course. It´s always good to have ones own viewpoint challenged.
@@SilverwingVFX Yea, I don't know but I always tend to like your C4D work more. Looks more realistic (in my eyes). You're doing great. I'm very impressed by your physics knowledge and creativity.
@@flopp4812 Thank you very much for your great response. I guess I have to work harder to make all my work stand out then 😇 Cheers and a great rest of the week and a good easter time to you!
Silverwing goes full tilt godmode and I am bubbling up the Anthropocene with foamy blobs today :D ... octanly speaking that is :)))) ... the puns aren't entirely my doing, obviously :))))))))))
P.S. I'd love to see a follow up for this showing the treatment for sponges and industrial foam - this is just amazing - so very grateful for the breakdown!!!
Thank you so much 😄 Great to see you here and thank you very much for your ongoing most generous support! The derivatives like Sponges / Industrial Foam are rather easy. Its just different bubble sizes / shapes. Also with sponges I think you can skip the surface part altogether and just use the volume. What would be amazing is to somehow find a hack to be able to bend and deform the volume so you can use it inside deforming geometry. I was not able to think of a solid way to do this yet. That I would say would be worth a follow up vid. Anyway it´s hard to follow such a well received tutorial with anything. And I am not that brilliant to have such good ideas every week unfortunately 😇 This was more like a "Once in a lifetime" thing ha ha.
@@SilverwingVFX indeed incredibly inspiring tut + great basis for experimentation! Definitely a major highlight as far as tuts go in general ✨ if my tinkering yields anything in the way of evolution I’ll most certainly will share it 🫧
Unfortunately not, but the way it works is very similar to Octane. You need the newest version of redshift with the Standard Volume in order to make it work. Then take the C4D Volume builder to make your object into a volume. From there on it´s basically the same. I have uploaded a RS scene to my patreon. With a bit back and forth this is definitely doable also on your own though!
There is a video on how to do this in Blender Cycles. ua-cam.com/video/4EZezYWyelM/v-deo.html If you want this for Blender Octane you can use Geometry Nodes to convert your object to a volume. I think there is a preset in the Modifier Stack. The only problem I encountered with Blender Octane is that the volume noises initially do not match up with the displacement. However the working fix is very simple: For some reason the texture space and the volume space do not align. So what you have to do is to rotate the texture space +90° on the X axis.
It really is. It´s a lot of shaders in disguise. You can do cheese, probably some other food as the inside of bread, sponges, industrial foams, clouds. Basically everything volumetric with bubbles of air inside 🙌
Thank you, great tutorial again. It was totally different from my approach. I used a Replicator to create the bubbles inside and on the surface of the foam mesh, and then Nested Dielectrics to “cut” the foam out where the bubbles are. 🗯< that is technically a bubble. I can't never find the correct emojis. I suspect YT might restrict my emojis :D
Thank you very much Kimmo, yeah it also took me a bit to realize that the approach was not to put in a lot of geo but to just use shaders in a volume. Of course it´s not completely perfect. Usually you would also have reflections from the inside bubbles that is missing. But it came out a lot more convincing than I thought in the beginning! About the Emoji. Thank you so much. Love the creative use of it because of restrictions. Looks like a busting bubble ha ha. Thank you so much for your ongoing support! ✨🫧✨

What an bonkers and amazing tutorial Raphael. The little explanations you do inbetween are so valuable. Thank you so much for your deep dive.
Thank you very much for your comment. I actually was a bit afraid I was explaining to little. Great that you find it a good balance 🙏✨
Perfect! Some months ago I tried to make a foam for a shampoo bottle and I was failed. So it means I will go back to this project again) Thanks a lot!!
Thank you very much!
Good luck with your project. Hopefully you can get there with this technique ✨
Thanks for sharing! Now to try and do it in Redshift.
Thank you very much for your comment. Let me know if you get anywhere. I tried to make it work in RS to. But only managed to go the route with the volume builder that is voxel based and therefore very resource intensive. If you find a way to use Shaders in RS volumes directly (not translated via voxels), let me know!
This is so cool! Such a smart way to achieve this look. Thank you for sharing yet another valuable tutorial with the community Raphael 🙌

A few months ago I spent many days building a very similar solution for a client project. It worked but ended up being hackier than this solution. Wish I had this back then. Thanks!
Thank you very much. Yeah I know those situations. Actually I was in the same situation before where I just built foam from displacement maps. I had this in mind back then but was not able to get there because the last component, a volume shader that allows density through textures, was missing. Luckily we are here now and whenever I have a request for foam again, I know a good way now.
Well it has its limitations too... but it looks convincing as a still at least🙌
@@SilverwingVFX Yeah, definitely more convincing than anything you could do with displacement. I went through trying displacement, making complex geo through Houdini and finally ended up with something similar to this in the end after seeing someone made something similar in Blender with Cycles.
🫧 Mind blown!! Love these Quicktips as usual. Was experimenting with making Nebulas in Cycles/Blender. Couldn't work out how to translate to Octane. . . . . I do now though. Thank you 🤗

Excellent tutorial as always, Raph! Thanks so much. I'll go try this out in Blender Octane tomorrow and get it to work there.
Thank you very much. Appreciate that you like it!
I have made a Blender Octane version too. Heads up. The noises in the volume and the Shader don´t align there.
So you have to turn the volume Shader +90° on the X axis for some reason.
Or, if you are Patreon member, you can download the Blender Octane scene from there... ✨
@@SilverwingVFXAt first I converted the mesh to a volume from the object menu, but couldn't get the textures to match at all. Finally downloaded your scene file and saw that you had done the mesh conversion through geometry nodes, which worked. I had actually thought of the possibility of doing the entire setup in geometry nodes. Between watching your tutorial and looking at the Blender Octane setup, I finally got the desired result. Thanks once again!
Amazing tutorial and really intuitive to follow!

Cheers and an amazing start into this week to you!
This is great, I love it! Exactly the stuff I'd love to see in Cycles too, to compare the workflows. Thanks, great work!
Thank you very much. Fantastic to hear you liked it!
I think the technique originated from Cycles. This is one of the thing I like better in Cycles over Octane, it´s good integration of volumes. It´s a bit more easy to do that effect in cycles actually as the volume of objects is not voxel based but also lets you use textures in it´s density.
I wish I had more time to do all the tuts for C4D Octane, Blender Octane and Blender Cycles. But there is a limit to how many tuts I can record in a week... 😄😇

Thank you very much Sleezy!
Yeah I know that there are even animated textures for foam out there that also work quite well in certain scenarios. But not in others.

unexpected, but such a pleasant solution! Raph, you are great!
Thank you very much. Yeah it´s not the first thing you would think of doing. I guess this makes it a but unique 😊
I did not explain the single steps to closely. e.g. what a Voronoi noise is doing. So I hope the audience can pick that up and understand it as is 😇
I thought it was vdb, turned out to be texturing, bravo!
Thank you very much. Yeah when I first started thinking about it I was sure that It could not be VDBs because it would have been insane ad a huge burden on the scene to put all those details voxels. I am therefore so glad that octane allows you that shader based workflow 🙌
Excited! Always wondered how to do this! Thanks mate!
Thank you very much Grischa.
It´s just one technique. There might be a lot of others out there. Though this works quite nicely 🙌

Feedback such as this make my work worth it 🙌
really brilliant
Ohhh, thank you so much. Glad you liked it 🙌
Very cool effect Raphael. I had an almost exact same setup back when I used Octane but it was dog slow because back then you couldn't just pipe a C4D Noise into Displacement without passing it through the Baking Texture node. So I had to do everything inside the Volume Builder 💀 while using the same noise for a geometry displacement (Displacer deformer). Because surprise surprise, if you use the same noise and seed inside C4D (like a field or something, using the CPU) and in Octane (on the GPU), you get different results. But your quality is insane, just so damn realistic.
Hey neoqueto,
thank you very much for your entertaining message. Yeah. I thought for a longer time how to make it work. And the biggest hurdle was that I could not use VDBs or a voxel based approach because it would be to resource intensive. All those small details in a volume are almost impossible to do on a voxel resolution level.
I also tried to make the same shader in Redshift and did not manage to get there. Because I did not find a way to control the shader with a texture and would have to go through the exact workflow you described above!
I did not even get to the point where the noise of the surface is defined differently then the one in the volume 😬
Great to hear you like the approach I took 🙌
Awsome tutorial! Thank you very much!

Hey Jerome,
thank you very much for your comment and thank you very much for your kind words. Yeah every once in a while I have topics just like this. In the mean time I make more low key tuts that are hopefully helpful as well.
I am still on the development with the opal shader. More off then on right now to be honest as I hit some serious walls. I am not sure if I will ever make it work to the standards I have in mind. Would be so cool though having an opal shader that really behaves and looks like the real thing. Maybe, like with the foam shader just now, I have a breakthrough. Fingers crossed for that!

Hey there and thank you very much for your comment. You are very welcome. Glad you like it 🙌
Thanks 🙏
Also thank you 🙌✨
What a great sharing. Very interesting way to create procedural foam bubbles. Thank you so much.
I am trying to follow your idea to recreate in Redshift. However, I have got a problem to match the bubble cut out and displacement. The shading happens after meshing (displacement) so they can't match. Basically, the texture used for displacement is not going to be the same as the vertices have moved. Just wonder why Octane doesn't have the same issue. Thanks in advance.
Hey hey and thank you very much for your comment.
I think it will work in RS as well. It might be that the noise is not matching up between the volume and the geo.
I remember I had to switch the RS object shader to input source "World" in order to match up with the volume. Not sure if this helps!
I guess there is always a slight mismatch between shading and actual volumetric noise because of the displacement / shading order. But it should still work half way decently and look rather good.
I have a working RS version on my Patreon if you are interested.
It will work in RS 3.6.00 and newer. This is because it has the new RS Standard Volume. Therefore it became possible to control shader density via textures. And therefore finally also create the foam techniques in RS. Though the volume noise can't be moved with the original Object, therefore no animations possible :-(
@@SilverwingVFX Thanks for your reply. Finally, I found out how could I achieve...^_^.

super cool bro thanks!

Please advise me, I have the same software version as you do.
Amazing!
Thank you very much 🙌
This is really cool, thanks for sharing Raphael!
In real life, wouldn't you also see the specular material refracting inner walls of the bubbles? I wonder if there is a way to create voronoi cell geo from the same noise?
Thank you for your comment. Yes you are absolutely right.
Maybe I should have been going a bit more explaining the physics of it...
Anyway. In reality you would have the reflection of all of those small bubbles but you would not have a volume. So basically what we did is accumulate all the small reflections that would happen in real world and distributed their energy to be a scattering (volume) instead.
Of course there is a difference in real world between scattering and reflection. But the smaller the bubbles are the more those two converge into the same behavior.
So for a more realistic shader it would be nice to have the inside of the bubbles also reflecting. Though this is not possible with our shaders as of now since a reflection needs a polygon wall and can not occur from a volume density change.
There might be some tricks you could use to sort of get there, but there are vastly complicated and, as far as I can think of, all have drawbacks:
I am thinking of creating a parallax occlusion on the surface material as well as some normal direction from the underlying noise to map the reflections of the surface to a depth that is seemingly inside the material with the orientation of the "bubbles" inside.
Though you would have to use stochastics to get different reflection layers on top of each other and since all of it is really only simulated on top you won´t get the natural obscuring of energy through the volume between the internal bubbles.
This is all well beyond my paygrade and also the reason I am struggling with the opal shader material so much as this is playing with ideas along the same lines.
Well, thank you for visiting my ted talk and thank you for reading ha ha ha.
Cheers!
@@SilverwingVFXThanks Raphael, always appreciate your ted talks!! Yes it certainly does seem tricky to get that fully in shader, I was imagining maybe tackling it with something similar to the flakes shader in RS (which I think is similar to what you mention with the parallax occlusion / noise / stochastics), but you're right that the volume won't interact properly.
I'll let you know if I ever tackle the full geo approach in Houdini someday haha. Best of luck with your Opal shader!
life saver!!!
Thanks so much. Super glad hearing that 🙌✨
Amazing! But now how do we up the level and make this amazing looking foam slide down the side of the bottle, for example? Let this be a consideration for your next tutorial :)
Thank you very much for your comment!
Yeah, that´s the big thing! In other engines such as Arnold or Karma there are so called rest positions that can anchor the noise to a meshes deformation. But this does not exist in Octane yet. I have thought about it a little bit and think this will be rather hard to implement with the available tools.
P.s. foam sliding down the bottle linearly will be OK. It´s just not possible, when the mesh deforms 😇
You are the Best mate...

Amazing...🎉 What if I change the shape of the object?
It should just update as intended.
If you have seen my posts on Twitter or Instagram I can also use other objects to hold the foam 🙌
❤beauty!!!
Thank you ❤️
Thank you for this great tutorial! Do you think it will work on a deformed object (alembic) without the material sliding?
Thank you for your comment.
The Shader is anchored to the axis of the object.
You would need something like a "reference position" "initial position" like in Arnold.
To my knowledge Octane doesn´t have a feature like this, So the noise will always slide through deforming geometry.
With alembic it also really depends how it was cached in the host app. If the geometry is non deforming and the axis is moving, then it would work. But if the axis is at the scene origin and the points of the geometry are animated, then it would start sliding.
Hope this helps to get a bit of an insight in the matter.
Cheers and a great start into this week to you!
Thank you for the answer, I will try something 🙏🏽

@@VaggelisRoubos Thank you very much for your comment. I faced the same problem as you did and It took much more time then I am willing to admit to come up with a working solution. However the working fix is very simple:
For some reason the texture space and the volume space do not align. So what you have to do is to rotate the texture space +90° on the X axis.

I duplicated my object, but my noise in the glossy material is not in the same pattern as the voxel =/
But great tutorial!
Thank you for your comment.
Make sure you have no transforms in your noise other then scale. Also your object axis need to be on the world origin for the noises to align!
Further, if your density is rather weak it can seem that your noise is not aligning because you can look inside the volume quite a bit so what´s going on inside the volume and on the surface can look disjointed.
I hope you will get there!
@@SilverwingVFX thanks, I'll try again
Why does my oc object label particle rendering not follow the object but a rectangle?
Hey there and thank you very much for your comment.
I think you are speaking of the step where you voxelize your object to make it a volume?
Maybe you have your Tag on the base object instead of the SDS Object.
Or you might have to large voxels and need to make them smaller.
Hopefully one of this will work.
@@SilverwingVFX I followed your tutorial tips for placing labels on the SDS, and in the OC render window it shows a rectangle instead of the actual object shape. The parameter settings for the label and object are the same as yours. Thank you very much for your reply!
this is amaizing stuf
Thank you so much 😊✨
Woah! this is nothing like i had in mind, Amazing and very eye opening, imagine how more powerful it'll be if we could gave something like pin material, i forecast a flood foamy bear renders for the coming weeks haha, what a trick, in some of my work in product viz, i needed to make a foam shader for a shoe sole and the way i went about it is the usual texture hacks with sss, however i had to change to redshift because with all the displacements in the scene i was constantly at least 4GB out of memory, i was working with a single 2080, fun times (sarcasm)
i was messing with projections on the side, i found out all the primitive ones work but also we can't really pin them to the surface of the geo so the best way to go is the XYZ to UVW, also triplaner works* + sticks to the surface and survives the bend deformer test, however, if you're not careful, your foam turns into swiss cheese or a cowboy hat
i wonder if there's a way to use geo as a cage to deform it with the surface, something like mesh deformer or FFD, all that aside, i think another solution is if in the future it becomes possible to use the standard volume into the medium input in material nodes, that way we can use the pin material tag to freeze it and use deformers on top
thank for unlocking a new part of octane, didn't know that the object tag is this powerful as a shading tool, wish you a great week ahead full of clean 🫧🧼renders
Hey hey. I was waiting for your comment. Thank you again for all your time and effort you pour into those!
About deformation:
I guess we would need a rest state / pin / initial state for that to work.
Right now the noise inside the volume does not even know the objects origin if we don´t explicitly tell it (Through linking the Null). So it´s unfortunately limited to non deforming geo.
Depending on the shoes sole I would probably go with an UV map and then with texture displacement. But it really depends how "foamy" the sole looks and how much of the inside you´d see.
P.s. does the Pin Material work?
I was under the impression that Octane does not have a way to pin materials other then UV maps. Would be really cool if I was wrong here. That would open a lot of other possibilities.
So for what it´s worth this should work for non deforming geometry, though I think there also might be problems with motion blur on fast moving e.g. sponges flying through the air, since the volume is only a translated texture. And I don´t think texture translations are supported by octanes motion blur.
I stated in a comment before that I really prefer cycles approach here having volumes and objects more connected so you get all the things you get in a texture on the volume too, and you do not have problems moving the object and the volume density noise to move with it. But well, you can´t have it all. There is always a thing that does not work and needs a workaround.
I am glad to have gotten so far as this is a very good way to make foam on static- or only slightly deforming geometry. It can get only better from here 🙌
A clean start into this week to you too ✨🫧✨ 😄
haha! of course i enjoy thinking and sharing my experience linked to the topics of your videos 🙌
unfortunately, i can confirm the pin material tag is not working for octane projections, however it works if you'd use the c4d projections on octane materials, even if the object has no UVs
for the shoe inner sole it had voronoi like texture, I'll share with you images once i dig through my old files 🙏
yes i remember that comment and it makes me wonder about the algorithmic limitations that causes these compromises and why isn't there a truly complete render engine (besides real life 😂) in existence, but as you said, it only gets better from here 🙌
Cheers 🫧🌟

Is it necessary to use c4d2024？no matter what mesh i use， only get a cube foam
Thank you for your feedback.
It should not be necessary to use C4D 2024. This should work with all C4D versions that Octane supports.
I had a comment earlier from someone who had the same problem. I could not recreate it unfortunately.
The only thing I can think of is eventually you have your voxels set to low and therefore your only see one cube.
If you find a solution, I would appreciate if you let us know what it was!

Hi there Silverwing! I got the Cinema 4D 2025 version and in the first steps, I don't have the Volume step length, but rather Volume step percentage. Default being 400%. No matter what put in, my cube is dark grey not white. Even in the Scatter, when I remove "density". What am I missing? Thank you
Hey there and thank you very much for your reply.
Octane in 2024.1 changed it's system to teh "Volume Step Percent"
You can find out more about it in my newest Video:
ua-cam.com/video/_Z1NMHxk9xY/v-deo.html
What you need to do as well is set Scattering to pure white, remove the "Density" argument from all the channels except "Density Channel"
And set Transparency to full black.
That should do the trick!
@@SilverwingVFX Thank you all is good now!
Is it normal though that it takes a lot out of an even almost maxed out laptop? Seems pretty heavy
@@Harrycat Volumes are definitely on the heavy side of compute. Especially with the spectral nature of Octane.
It still depends though.
If it feels rather heavy and laggy, then I advise for increasing the step percent until you see density changes that you don't want. This can increase performance a lot.
Basically what I say in the former comment linked video.
@@SilverwingVFX I did all of the steps but it remains grey, and the range node won't connect, weirdly. I'll downgrade and try.
edit: fix for range node is, dragging in range node then you can add an 4dnoise as the value, etc. - still dark grey rather than white sadly.
edit: something that fixed the grey was using the emission, mode to density, weight to like 0.7
@@prev Great to hear you sort of got there.
What you are doing right now is making the volume a light and therefore avoiding it becoming too dark.
As everything is allowed that works at the end, this is a good solution if it works for you. Though of course this is not physically correct as foam is usually not emitting light 😇
I am sure there is a plausible cause for why you are experiencing this darkening 🤔🤔
It might be the density channel that is added to the scattering per default.
Other then that, some causes could be:
Too high Density (too small value in the Volume Step Percent. 100% should be a good value, but Octane has not been "trustworthy" in it's new version and it strongly depends how you have generated your volume. If it's not a "Mesh To Volume" then the scene size also plays a role how much percent you have to set.
The render-kernel is not set to Path Tracing but direct lighting.
The Scatter Depth is too small (also note that the Scatter Depth is limited by the Diffuse Depth) I recommend setting both to 8-16 depending on your system resources.
The GI Clamp is set to low. It can make Volumes rather dark. Values from 3-10 should work
Other then that I am out of ideas for now. I would have to have a look at the scene.
I hope one of the above points work for you though 🙌
Best!)))

My octane tag doesn't have Particle to render; Any work around?
I think it might have something to do with the Octane version that you are using.
It came in around Octane 2022. If you are using a version before that, you do not have the possibility to use "Mesh To Volume"...
Thanks for the quick reply. Yes that is the correct answer, old version; i did found half of a work around using voxels with the volume builder tag but.. still stuck tho. You have a great day!@@SilverwingVFX
Can you show that in redshift?
Thank you for your comment.
I tried that in Redshift. But I could not make it work yet. Possibly because of my limited knowledge there.
The only possibility I found there was to use the C4D volume builder and use a texture field with a noise in there. But that makes everything dependent on voxels and not textures alone to control densities. And therefore this approach will be very resource intensive.
I will let you know if I find a better way.
hello, i tried follow your tuto to make this amazing foam material, but i working in octane for blender, usialy its not that big difference, so most of materials i can replicate in blender from C4D.
But this time i am struggling, cant find the way to make Mesh to volume in blender, its quite more complicated i gess. Can enybody guide me how to mimicking this sheder in Octane for blender? thank in advance
Thank you very much for your comment and your question!
The way you would do this in Blender is not via Octane but via Geometry Nodes.
There is a Mesh To Volume Preset.
I have made a Blender Octane version too. It's available on my patreon. Though you should be able to get there without having that scene.
Small heads up. The noises in the volume and the Shader don´t align there.
So you have to turn the volume shader noise +90° on the X axis to line up for some reason.
@@SilverwingVFX octane geometry nodes? Right? Ok I'll try ☺️
@@dmytrosurin1384 Blender Geometry Nodes. Has nothing to do with Octane.
You just need a way to convert a polygon volume into a VDB. IN C4D Octane can do this. In Blender Geometry Nodes can do that.

Hope this helps 🙌
@@SilverwingVFX I am so sorry I don't understand, I using octane render in blender, not cycles, that's why I looking tutorial for octane in C4D , usually it works, but can't get volume same way like in C4D.
@@dmytrosurin1384
I think I understand you. That does not change my answer.
Let me try to explain this:
For the tutorial to work you need a volume with the same shape as the mesh that creates the bubbles.
It does not matter where the volume is coming from. Whether it's created by Octane or Blender. Octane Blender does not have a "Mesh to Volume" so we need to use Blenders function for it.
A Volume is nothing Octane specific. Think of it as an asset, just like a mesh. You can generate it and then use whatever render engine to render it. In your case this is Octane.
When you have the volume you can then use Octane Shaders to bring it into the renderer.
And if you can't get there, as I said, I have a blender Octane scene for the foam shader on my Patreon 😇
👍👍👍
🙏🙌✨
Your renders turn out much better when you're using C4D
Thank you very much for your comment!
I would argue against it. At least technically Octane is doing exactly the same in Blender then in C4D, so there should not be any difference in quality.
Maybe it´s the fact that I have much more assets ready for C4D then for Blender, as I have been using C4D for a lot longer time now 🤔

P.S. I'd love to see a follow up for this showing the treatment for sponges and industrial foam - this is just amazing - so very grateful for the breakdown!!!
Thank you so much 😄
Great to see you here and thank you very much for your ongoing most generous support!
The derivatives like Sponges / Industrial Foam are rather easy. Its just different bubble sizes / shapes.
Also with sponges I think you can skip the surface part altogether and just use the volume.
What would be amazing is to somehow find a hack to be able to bend and deform the volume so you can use it inside deforming geometry. I was not able to think of a solid way to do this yet.
That I would say would be worth a follow up vid.
Anyway it´s hard to follow such a well received tutorial with anything. And I am not that brilliant to have such good ideas every week unfortunately 😇 This was more like a "Once in a lifetime" thing ha ha.
@@SilverwingVFX indeed incredibly inspiring tut + great basis for experimentation! Definitely a major highlight as far as tuts go in general ✨ if my tinkering yields anything in the way of evolution I’ll most certainly will share it 🫧
you are god!
Thank you.
As I say in the video, the Idea is not mine 😇 I just recreate it.
I appreciate it though ✨
I hope next tutorial will be "Silverwing Quickish-Tip: Redshift Foam Shader (C4D Redshift)" with latest redshift version
Unfortunately not, but the way it works is very similar to Octane.
You need the newest version of redshift with the Standard Volume in order to make it work. Then take the C4D Volume builder to make your object into a volume. From there on it´s basically the same. I have uploaded a RS scene to my patreon. With a bit back and forth this is definitely doable also on your own though!
Could i use blender?
There is a video on how to do this in Blender Cycles.

If you want this for Blender Octane you can use Geometry Nodes to convert your object to a volume. I think there is a preset in the Modifier Stack.
The only problem I encountered with Blender Octane is that the volume noises initially do not match up with the displacement. However the working fix is very simple: For some reason the texture space and the volume space do not align. So what you have to do is to rotate the texture space +90° on the X axis.
This is actually a Swiss Cheese shader in disguise.
It really is. It´s a lot of shaders in disguise. You can do cheese, probably some other food as the inside of bread, sponges, industrial foams, clouds. Basically everything volumetric with bubbles of air inside 🙌
waw
Thank you 🙌

Yaaaaas 🧼✨🫧✨🧼
🥂🛁🧽
Ha ha, that's also a very creative interpretation of emoticons. But they all fit 🙌✨🫧✨🙌
Me as redshift user... 🥲🥲🥲 Nice tut, but Coffee foam is better, I am going to grab a coffee... haha. Nice tut!
I think this can be also applied to RS. Haven´t tried it though.
P.s. coffee foam for the win ☕🫧
Thank you, great tutorial again. It was totally different from my approach. I used a Replicator to create the bubbles inside and on the surface of the foam mesh, and then Nested Dielectrics to “cut” the foam out where the bubbles are.
🗯< that is technically a bubble. I can't never find the correct emojis. I suspect YT might restrict my emojis :D
Thank you very much Kimmo,
yeah it also took me a bit to realize that the approach was not to put in a lot of geo but to just use shaders in a volume. Of course it´s not completely perfect. Usually you would also have reflections from the inside bubbles that is missing. But it came out a lot more convincing than I thought in the beginning!
About the Emoji. Thank you so much. Love the creative use of it because of restrictions. Looks like a busting bubble ha ha.
Thank you so much for your ongoing support! ✨🫧✨
