In this C4D tutorial I'm going to show you how I approach post-compositing with Octane's render passes. I'll use both After Effects and Photoshop to show the two different-but-similar techniques. Even thought I work with Octane, this comping workflow applies to pretty much any other render engine, I've been using the same method with Arnold and C4D's Physical engine.

Honestly never thought about compositing beforehand, this is a great way to get started, really appreciate it.
Hell yeah bro, compositing is essential!
You are a natural teacher - this is a rare thing. Thank you for sharing your talent.
Damn that's a cool compliment, thank you!
I am always looking to improve my renders and this tutorial really helped me take my projects to the next level.
Dude hell yeah, I'd love to see the improvement!
It's amazing how much help I'm receiving from these tuts
Phenomenal!
2:50 - lighting passes can be used to modify the strength of a certain light in post. so eg if you set up an area light with light pass id 2, and you render out light pass 2, you can use that pass to make that light brighter/darker in comp without changing the strength of the other lights in your scene.
Absolutely! Also for changing color of lights in post which sounds insanely useful, but I literally never had to do that in 4 years of working with CG. I was explaining much more when I originally recorded but decided to cut down a lot of information so the video won't be an hour long lol
I decided to only share my usual process of how I actually use the passes to comp, and what would be more commonly used in general renders.
Thank you for the comment!
No thumbs down! You are definitely deserve this results. Good job!
Haha appreciate you, but you KNOW you made it when you got haters!
Glad I stumbled upon this in my recommendations! Just subbed, looking forward to more man!
Hell yeah, thank you buddy!
Awesome. Thank you dude! I've been wanting to know about proper compositing like this for so long.. really useful! thx
Glad to hear that!!
Thank you for doing this! I've been so confused on how to properly composite passes
Happy to hear it helped buddy!
your tutorials are amazing man! You are teaching me a lot!
Thank you!
Really happy to hear that my guy
Very cool tutorials my guy! Helps me out with learning all this stuff and starting out with 3D in my edits
So happy to hear this!!
THANK YOU! You answered all the questions I had in one go!
Amazing!
Hey dude, just wanted to say : really cool tutorial keep going !
Really appreciate you!
Another banger! Much appreciated!
You know it brother!
Im a big fan of your tutorials already!
Thank you brother! Been a big fan of your channel and your personal work for a while!
really great tutorial
My pleasure buddy
Oh my god thank you! Im so in love with your channel
Haha appreciate you buddy!
Thank you for sharing !!! It's great.
Amazing more of this content pls!
wow this is another level. thank you!
Thank you!
WOW THIS IS WHAT I'M WAITING FOR. THANK YOU SO MUCH 🤍
Yeah boi!
Thank you for this man.
You're welcome bud!
Great Tutorial. One tip: When importing the exrfiles into AE you should set the checkmark at "create composition". That way AE extracts automtically all exr passes for you inside one comp.
Oh WOW! I was not aware of that. Really helpful, thank you for this!
I think it's still good for everyone to see how to manually set it up just to get a deeper understanding of how the process works, but as a general workflow this is extremely time saving!
Dude wtf, I didn't know that either. That's so timesaving. Thanks!
Very nice!
Thanks, I didn't know that.
Great stuff!
Thank you!
Really
interesting tutorial thank you
Absolutely my dude
Thank you!🙏
Wowow this is really handy!! thanks a lot
Glad I could help bud!
Mind blowing. Thanks
Haha happy to hear
thank you very much
Such an awesome tutorial! Been doing some research on render passes with Octane these last couple of days and this is awesome :) Any chance you could do a Part 2 including the ZDepth pass? I've been doing some simulations lately, and that one seemed like an essential pass I should work with. Thank you!
Yeah! Definitely will, I'll go over some of the passes I didn't in this one
Super cool video! Thanks for sharing!
Btw AE 2021 handles importing exr sequences pretty well. Barely and inconvenience :). It can even make a contact sheet from all the passes.
Oh damn I should look into it, I'm so used to this method I probably didn't even notice the update!
Great Job! Thanks a lot :)
You're absolutely welcome!
That is a great tutorial! I would LOVE to see something similar for Apple Motion :(
Didn't even know about Apple's Motion. That's amazing. If I ever get into it I'll probably show how, but I'm guess the workflow is pretty similar. However, I really don't know!
Great tutorial! Could you make another on how to export volumes with render passes?
Yeah I'm gonna make a part 2 that includes some of the other passes that I didn't go over in this one
Hey man, Thanks for the tutorial. Can you recommend an After Effects Course to learn Compositing in particular.
I needed this. Thank you amazing tut do you know how to bake textures with octane as theres no real tut out there that explains the process the way you drove this tutorial home.
Hey thanks! As for baking the textures, there's a little process but it's fairly straightforward. Check out this video which explains exactly that:
ua-cam.com/video/7tTLH8wqMYQ/v-deo.html
You are awesome
Nah you are!
Thanks. Do you have a video on how to ensure the ACES Color Space syncs between AE and C4D?
Yup! right there on my channel, it's the one I uploaded after the video going over the overall Color Management for Dummies
hey! great video
But I can't export all in PNG separated :( in the save menu (I'm using octane for cinema4d s24) I can't uncheck "multi-layer file" idk why
Best compositing tutorial so far thanks man! Using the" Object Color Layer" pass on object hidden or covered by other objects (even covered by a glass object) doesn't seem to work, do you have know a work around? It seems to be similar with Crypto...
Yup you can't get matts of of transparency. It's a flaw of the system :(
My multilayer passes are completely black in both the picture viewer and in after effects, I'm using a later version of octane that uses AOV groups, do you have any idea why they are completely black black on the multi-pass layer view in the picture viewer?
Hello whats the difference between the Ambient Occlusion Pass and Shadow Pass?
gold
More like rose gold am I right
Oh I just realized I thought it was a comment on the Metallic surfaces tutorial. The pun doesn't make sense now lol
Good tutorials!! Now I use the newest version 2021.01.2 there is AOV Manager
And when I check the enable Aov Manager, the render takes 32bit images (renderview was 16bit) ,,
Yes I need to make a new video about the AOV system since it completely changed !
how would this work with ACES?
I've only just installed octane and my render settings look a little different from yours. The option for material pass isn't on my screen. Anyway I can fix that? Thank you
Yeah the new Octane versions have a different setup for passes which is called AOVs. The beginning of this tutorial isn't relevant for the new Octane versions, but the rest (The After Effects and Photoshop workflow) still apply the same.
Hello. Very great tutorial ! I have a question though. I use a lot "highlight compression" in my camera imager tab. I noticed that in linear tonemape type and color profil, this highlight compression isn't saved in the final image. The image is too contrasted and does not keep all the subtle nuances. I saw you using this highlight compression in other video. Do you have any tips?
Hey, thanks! Yeah so if you export in Linear, the highlight compression won't work. I only use highlight compression when I know I'm not going to do heavy compositing.
When I export Linear, I just need to adjust the lighting so the highlights are not burned. They can be a little hot, because 32bit Linear will be able to adjust the highlights in post and bring out some of the information in the highlights.
Also when rendering the beauty pass in Linear, don't forget to go to the Color Management tab in the "Interpert footage" of the image inside AE, and tick the "Preserve RGB" option. And then adjust the gamma to 2.2 with the Exposure effect.
But yeah, at the end of the day without highlight compression you just have to lower the exposure or adjust the lighting so it's not burning the image. It can get tricky but sometimes you need to render a frame out and import to AE, usually it looks way less burned and contrasty because the Live Viewer is not as good as AE in handling color depth.
Thanks a lot for the answer. Next Time i use After, things will get more clear
@@benvesse Hopefully so, let me know if you still have questions!
Great looking tutorial,
Just one question, would it be possible to make a pass for the "luie vuitton" logos?
I was struggling to find it, starting to think its impossible :)
Thanks a lot :)
Man that's a good question. I was looking for that too but so far no easy answer. I'm sure it's just cuz i'm not looking in the right way. Once I figure it out, I'm running here to tell you.
@@NewPlastic I think the new Octane 2021 release, with it's custom AOV system will bring a solution. 😊
@@Stefan_Vid Sure do hope so!
Hey! i have a SSS object that gives out these caustic, colored shadows on a plane. I'm gonna composite this onto live footage, but i cant find an option to make the shadow catcher pass out a colored shadow. it just gives me a black shadow due to the fake shadows turned on.
Hmm interesting question. Let me test it and get back to you
@@NewPlastic thanks a lot!! Wasn't sure If you'd reply 😅
Bro, is there any chance you will make a similar video of your comp process updated to 2023/24 AE, which better supports ACES workflow, etc.? 🐐🤍
My man! Yes I actually have one on my channel, it's called After Effects Workflow for AgX and ACES
@@NewPlastic 🐐cool thanks homie 🤍
Hi there, that you on the 4:39 pick 2 files, and I'm getting one after my render is finished in C4D. I believe that I've set everything as you did. Can you tell me what am I missing? Tnx
Hey, make sure you name the passes file a different name, and also make sure you give the passes file an absolute path like c:/users/myuser/projectfile/renderfiles_mult.exr
For some reason if you just write the name of the file, Octane won't save it, it needs an absolute path
Try that see if that worked
@@NewPlastic If you mean in the render settings - under the Save - I wrote as you said, but I still have the same result. Do you do private consultations? I'm willing to pay for it.
@@MiroslavGeorgijevic I do have a tier on my Patreon with a 30 minute session per month so you can def check that out!
Also, if you're using the newest Octane version, they have changed the system to an AOV based pass-system which acts different. So unfortunately if you're using the newest version this tutorial is not that accurate. I will do a new one very soon.
In octane should you leave the camera on rgb or linear? Also do you adjust the gamma in octane or leave it at 2.2?
It's usually best to work on Linear, and if you work on linear mode you have to set the Gamma at 2.2.
Only times I don't set it at linear but as sRGB is when I Compress Highlights. That doesn't work with Linear RGB so if you compress highlights and export as linear, the final image won't have compressed highlights.
@@NewPlastic Thank you so much for getting back to me. I've always been overwhelmed by utilizing render passes, and this tutorial was so easy to digest. Keep up the great content
Is it possible to do this in a video?
Yes absolutely, just do the exact same step on a sequence of EXRs instead of one EXR.
As far as a video file, you can't render passs in a video file, you'll have to export an EXR sequence. But you never want to render into a video file anyway, you always want to render to image sequence.
👏👏🙏🙏
New updated video about how to do this with the new AOV system coming next week!
@@NewPlastic Can't wait dude. Your tuts are essential!👌👌🫡
Kinda just skips over some important things. Cryptomattes are key. I would do another vid on all this tbh
Yezzir cryptomattes are a whole thing. Honestly up until that video I was working only with Object Layer, so I couldn't even dive that deep into Cryptos but I've been using cryptomattes regularly since, funny enough.
There's many other things I haven't gone into, which I told myself I'll do another video on. This video was really focusing on the basic essential passes I always render for juicing up in post.
@@NewPlastic Yeah I think also a tutorial for render passes for animations would be good. I find that most tuts are for a single images. For example if I apply all the settings from this tut to an animation it takes my render time per frame from 3 mins to 4mins. I have a feeling Cryptomattes are faster than Object Layers.
@@Willopo100 There might be a chance that crypto matte rendering are faster, I haven't noticed a difference actually. A while ago you used to have Render Masks or Layer Masks or wtvr and that was super slow, but any other method doesn't really seem to affect render times as much for me.
I usually deal with animations so this is my method for animations too, there's not much difference in terms of importing one image vs importing a sequence of images.
Are you saying that for you rendering without passes takes 3 minutes per frame and with passes takes 4 minutes?
Too fast ☹️😖 definitely not for noobs (like me)
Yeah I agree, the way I approach tutorials is how I enjoy watching them, thorough yet very quick. These tutorials are oriented to people who already know their ways around C4D, but I'm hoping anyone can learn something.
Are you my mummy?
Yes son. Wear a sweater it's cold outside.
