Hey, no, that's where this workflow is a bit more simple than ACES. Base color/diffuse maps should be loaded as srgb, everything else is raw. This is because AgX is just a view transform applied on a linear render. Someone mentioned getting good results from rendering ACES images and applying the AgX transform to them afterwards as well. Haven't tried myself, but it sounds interesting.

Hi, thank you for your comment! If you have time to spare, it would be really helpful for me if you could show me specifically what those errors are. You mention "masking" errors. What do you mean by that? As far as the wrangles, I built the project files while recording these videos and didn't intentionally change anything in between finishing the recordings and uploading the project files. So if there are any inconsistent wrangles, I would love to either fix them or write a note about the change so people can follow along. Could you point me to a wrangle in the project that has changed from the last time you see it in the recordings to the 01_flowerTutorial_004_end.hiplc file? A thing I should have mentioned, and will work to update in the descriptions (potentially add a readme file) is that there will be warnings about incomplete asset definitions, but because the assets are unlocked for editing, this warning doesn't stop anything from working. Thank you!

@@halyna3D hey, you could definitely try. This method doesn't scale well, but in my experience ABC or USD wouldn't either because you would need to bake the positions of thousands of spheres instead of thousands of points. I have a two part video series explaining a custom method similar to this where you bake point positions as an exr sequence for Niagara to read. That method allows for up to 2 million particles and is relatively fast to export.

That sounds interesting! I'll have to give that a go

@dirtcreature3d hey, thanks for the tip! I found some vids on doing that, specifically for CG renders. can you share whether you use some specific settings in Color Space Transform node or they wary based on the shot? from what I've found in "Setting up AgX on DaVinci Resolve" video, the author recommends keeping Input color space as ACES (AP1) and Input Gamma as Linear (the same as it's done with ACES), but Output Color Space is set to ARRI Wide Gamut 3 and Output Gamma is ARRI LogC3. my shot looks nice and I wonder how other people do that. :)

@@iamopia yeee im pretty sure the vid your referencing is the one I watched as well I use the aces transform node, input set to Aces CG and output set to arrilog and then DCTL node after with the AgX profile selected

Yes it does!!

Thanks for that!

Hi, thank you for your feedback. I initially marked the tutorial series for beginners, but after receiving community feedback, I updated it to be marked for intermediate users. I think going through one of the beginner series like NineBetween's Houdini Isn't Scary will help this flower series make more sense. Something that will certainly help you, though, is to download the project files so you can compare my setup to your own along the way.

Thank you Magnus!! Will do, boss :D

I would say it's good enough for most things at this point. I'll be sharing more quick tips over the coming weeks that will hopefully help people coming from Redshift work with Karma

@@DannyLrsn That'd be amazing. Thanks! Subscribed.

Hi, what would you like to see from Houdini to Unreal?

@@DannyLrsn Hi there! Anything you can create videos on is so valuable to me because I am very new to the Houdini to Unreal Engine workflow. Since you asked for particular topics, I'd like to see hair simulation with animated vertex color like in this [video](ua-cam.com/video/G0TkJIHlnRo/v-deo.htmlsi=vmDNYl21Pu0ZRMRK). I tried to export hair from Houdini to Unreal, but it seems that animated vertex color is not working by using attributes. Hope you have a great day! 💖

You're welcome :)

You're welcome!

Thank you! I have a few of these planned so there will be more to come in the near future

Unfortunately I don't know Unity. I would imagine you export as alembic to get geometry caches from Houdini to Unity

Hey! I'm sorry to hear the kinefx part was confusing. I think it would have been beneficial for me to explain it slower and show simpler examples to help clarify the base concepts before moving onto the flower setup. It might help you to download the project files (free in the description) to break down what's happening in your own time. Regarding intersection: The idea is to move the petals from a state where they have zero intersections (deintersected pose) to the bud pose where there might be intersections, through to the bloom pose. All of this should be simulated so the solver can hand collisions and intersections throughout. I hope to share some more Karma related content in the near future. Excited to see the work you make!

Thanks man .. I think your explanations are great... I think the Kine FX part is just too advanced for me, cuz I don't have any experience eith this

Happy to hear it was useful for you!

@@DannyLrsn The clear explanation even gave me some ideas for extension, and I will do more experiments in other projects. Thank you！

@@hendasheng that's awesome! Feel free to send me your work on IG or something when you're ready!

@@DannyLrsn Definitely! Cheers!

Hi! I think you would benefit from downloading my project file. Compare the group expression node in my file to the one in yours and see what's different. Good luck!

Then you probably typed it wrong. It's "curveu" (curve U). And you probably missed when he set it to "Points" at 1:50. It's the very first thing he did after adding that Group Expression node.

Solved clipping problem! I didn't assign bottom attribute.. I got new problem ;-; my flower bud is now well organized, but when it perfectly bloomed, petals are streched like melted cheeze.. Is this problem of Cloth bend-stiffness value?

Looks like you need to increase the stiffness in the stretch parameter… if you don’t it’ll look like rubber or a slimy material, it seems that’s the problem from your description.

@@RubaoAbranchesFilho Thanks a lot! I increased substeps in vellum solver and solved problem! I also increase stretch stiffness parameter too :)

Haha, let's see if I ever figure out what I wanted part 4.5 to be. Glad the tutorial was helpful for you!

Thank you for the nice words!

oh well i guess i found out, i just changed the line of code in the "growth animation" node from "float mask = fit(map, p, p + t, 0, 1);" to "float mask = chf("mask");" and i'm animating the slider to get my transition.

@@MrLinvalT Hey thank you for the kind words! Yes, that seems like a solid solution. If you still want a little variation in the growth, increasing the "Transition Width" can make the transition even more uniform. Would love to see your results when you get there :)

@@DannyLrsn Absolutely i'll send them to you once i finished my killer set up hehe !

Thank you! I think you explained it yourself. Houdini has a "Divide" node that can triangulate meshes for you. Maybe use that on the results on the rbdmaterialfracture?

@@DannyLrsn thank you Danny, got that fixed :)

@@EliRezik Awesome!

Hi, DL Merge Animation Sequences is a node that I created. I vaguely explain how it works in the video so you can either reproduce it yourself or you can download the project files and grab the node from there. Note that when you open the project file it will say something about a missing asset definition, but this error doesn't actually mean anything because the asset is unlocked. Hope that helps!

@@DannyLrsn Okay, thanks for explaining! I'm sorry, I don't understand English well, so I didn't understand what it was about in the video. Now it's clear, thanks again!

@@suboer No worries! Happy to help.

Hi Luke! Thank you for your kind words. Unfortunately I don't have access to a Mac to test the tool. I would guess it has to do with the ffmpeg path in the ffmpeg node

@@DannyLrsn no problem man great tool! ok I managed to track it odnw through the node graph and get it to render out jpegs into the flip book my next 2 questions are is it possible to change the resolution or to get higher quality flip book out put ? and also my nose won't show up in solaris network only .obj any ideas why ?

@@3lukemoore Awesome that you got it working! I don't see why it wouldn't show up in Solaris if you have the LOP HDA in your otls folder. In terms of resolution, at the moment it is dependent on the resolution of your viewport. I might rework it in the future so it opens a new viewport with a custom resolution.

@@DannyLrsn I have the dl_flipbook.1.5.hda in my otls folder, not sure about lop .hda though ?

@@3lukemoore When you get the project on gumroad, there are two HDAs. One object_DL.dl_flipbook.1.5 and one lop_DL.dl_flipbook.1.3. The lop one is for LOPs. However, I no longer have access to the FX license so the LOPs HDA is limited commercial license.

Also at 11:59 there seems to be a slight time-skip: For anyone lost: Make sure you have two sets of the "Object Merge" node. The first Object Merge node will be to get/reference the "OUT_capturedPetal". The Second Object Merge node will be to get/reference the "OUT_deformedPetalSkeleton".

Hey, thank you for clearing up some of these areas that I didn't pay enough attention to! I'm sure it will be very helpful to other people

@@DannyLrsn no thank YOU for your tutorial Danny! I know making and editing tuts are hard enough for Houdini. Hopefully I’ll get through the rest of the videos soon! :)

Thank you for the feedback. I agree, it is a bit too chopped up. I'll work on doing this better in the future!

Hi, note that in the wrangle I change the expression to say @P.x = amount; Hope that helps!

Maybe check if Houdini consistently crashes when you put down a Bone Capture Proximity in other situations as well. Also worth checking if you somehow have millions of points on your petal so it crashes because the calculation is too complex. If it keeps being a problem, you could be on a Houdini version that has a problem with that specific node. In that case, upgrade or downgrade your Houdini version. Hope that helps!

Hey. I don't really know what you mean by reading the uvs square by square. In SOPs, you can hold spacebar over the viewport and press 5 to switch to UV view to verify that your UVs look as expected. Otherwise, download my project file and check the uv and uv2 vertex attributes. Compare that to your own project to see if there might be something you missed. Hope that helps!

@@DannyLrsn I got it to work, had to rewatch 3.5 and I magically changed. now I'm having some trouble with the displacement using unlit as a preview doesn't let me preview. I compared to your file and nothing changed. Could this error be because I have the education version?

@@LittleMountain111 I really doubt that your license has any say in whether displacement works. In terms of using the unlit surface node to preview, remember to take the output of that and plug it into the shader where the standard surface is by default. Maybe watch the part where I explain it again and pay attention to which outputs go to which inputs. If displacement doesn't seem to work, try to increase the displacement scale by 10x to verify that nothing happens. Then check that you actually have values going into displacement by using the surface unlit. Hope that helps

@@DannyLrsn go it! Had to update Houdini. ty for the tips

When I made my lotus, I increased the bend stiffness on the cloth constraint quite a lot. The intersections show up because the pin constraint wins against the collision check. You can decrease the stretch stiffness of the pin constraint. You can also increase the collision iterations in the solver to help the collision solve take priority over the constraints solve. Hope that helps!

The mistake was actually very simple. I didn't connect the object merge "get_capturedPetal" to the null named the same.

Hey, sorry about the late response. I'm happy you managed to figure it out!

Glad to hear that!

You're welcome!
