Important: In AE choose a color profile (likely sRGB) and then hit "Linearize Working Space"
This gives better results then leaving the comp to None and only choose "Blend Colors Using 1.0 Gamma" See screenshot here: silverwing-vfx.de/Download/AE_...
Since everyone was eager to learn about the 32bit Workfow in the latest Twitter poll I upload this video.
This is going over the fundamentals of 32bit or "float" image generation in rendering (Octane) and the compositing Process (AfterEffects)
If you wonder why this video has a slightly different format to it:
I made this video for the Quarantin 3D. They are streaming every Saturday and Sunday evening on Twitch / quarantin3d
I hope it gains you some insights in the workflow and you like it.

Good news, in Octane 2020.1.2 DWAA & DWAB lossy EXR compression now also works correctly with cryptomatte passes which now get stored in a lossless format in the same file.

Hey Raphael, thank you for your workflow insights! In regards to the question at the end for the depth converter in After Effects: I always use an Adjustment Layer on the top of the Comp with the Levels effect and set the "Clip To Output White" to "On". This way the Media Encoder interprets the colors the right way and you dont need to use a 8 or 16 bit effect. Hope this helps!

@@SilverwingVFX Yeah man, I was especially impressed with how you rendered your light passes and able to adjust each one individually! I think Corona is capable of this as well, and now I am kicking myself for not doing it sooner. Crazy how much more control you can get. I'm on the final stretch of finishing a huge project. It's been a constant struggle lighting areas that get blown out. Wish I would have known about the light pass technique sooner haha. Thanks again!

@@mattrittman Yeah that´s a great way to comp. I have done this with my Gameboy and whenever I had a bad reflection because of a light I just animated it to blend off and on for that section and it worked great. If you want to even go a step further you can add ACES on top of that workflow and you will have even better highlight handling. I have a tut on this workflow as well. Cheers and happy rendering to you!

@@SilverwingVFX Oh wow okay, I will have to watch your video on the ACES workflow as well! I tried ACES briefly in Corona and it seemed to make the image very high contrast, but I think I need experiment more with it. I hear people talking about how great it is all the time! Can’t imagine how complex your game boy video probably was in AE haha. This AR15 animation is 8½ minutes long, and even it is pretty complex. I’m super burned out and it’s taking a toll on my mental health. I don’t think I could do another video this long again. I don’t know how people do it 😩.

@SilverwingVFX
@SilverwingVFX 2 жыл бұрын
To my knowledge this is just not possible to have denoising on other channels then the beauty and the channels that contributed to it (e.g. diffuse, reflection, refraction etc. So single light passes are unfortunately not available in a denoised version. I personally never denoise my final render. I use neat video in comp if there is remaining noise.

How do you set up something like these little lights inside the object? I thought it is emission but then you wouldn't be able to use it as part of light pass right ? What would be best to use for emissive materials? Thanks!
@SilverwingVFX
@SilverwingVFX 3 жыл бұрын
In Octane you can declare any emission as part of a light group. There is a "Light pass ID" in the Emission node. I usually use Octane Diffuse for Emission. If I do Screens where you also need a reflection on top I am using the universal material. Hope that helps. Cheers and a great start into the week for you!

Thanks so much that was so informative! Im still at a loss though and i hoped copying your settings exactly would let me find my problem but it didnt. Im working in linear, set everything the same way you did but in picture viewer and in AE it looks like its been converted to 8 bit sRGB (blown out highlihgts, contrasty and oversaturated). Any idea what could be the problem?

Thank you for this walkthrough, Raphael, more useful than what I thought. I'm a long-time Octane user, I've tried Redshift but I didin't like too much and discarded it. May I ask your opinion about these 2 rendering engines, how do they compare? I see Redshift being used more and more from a lot of production companies. Thank you!
@SilverwingVFX
@SilverwingVFX 4 жыл бұрын
If you trying to figure out what render engine is the best of you the best person to deciede that is you. I am with you in the observation that more and more studios are switching to Redshift. I can imagine that this is mostly because Redshift can be integrated into existing pipelines then Octane. And based on my observations its more stable then Octane currently. I personally like Octane for its uncompromising render quality and simple setup. But as I said in the beginning the best way to know what you should use is to test it yourself and maybe look around what studios you want to work with and what renderer they are using.

Thanks for this :) very informative. I noticed you do not use linearize working space but instead use the blend using 1.0 gamma checkbox. this means only layer blend modes work in linear gamma but everything else (like effects) will work in srgb gamma. did you do it on purpose? this will mean that realistic results might not be as easy to accomplish. on the other hand, linearizing Ae's color space takes getting used to...

Hi and thanks a lot for your comment. I indeed back then did not use linearize working space. This was because the e.g. the curves effect is rather hard to handle in linear space. But since I switched to ACES there is no way around using proper linarization as you suggest! Thanks again for pointing that out! Cheers!

So when exporting the final image, why can't you export in 32 bit? Why does it have to be 16 or 8 bit?
@SilverwingVFX
@SilverwingVFX 3 жыл бұрын
You can export it in 32bit of course. But you can´t watch it with any normal picture viewer / video player and if its a video is usually heavily compressed 8bit. HDR being the exception with 10bit. Exporting in 32bit mostly makes sense if you delivering to HDR color grading which then will save the files with 10 bit + HDR metadata.

Nice video Raphael. Btw why don't you set up color working space in AE and linearize it? It will also enable gamma 1.0 for blending. As far as i know it's better to set up even if you use linear files for compositing. Also why do you use solids as adjustment layers?
@SilverwingVFX
@SilverwingVFX 4 жыл бұрын
Hi there and thanks for your comment. Yes you should setup color spaces if you work for any define workflow e.g. TV production in rec709. I guess for me its more then anything else a ghost of the past back when it was more usual to setup AE this way. You could argue since I am producing for the internet so I sattle for the smallest standard sRGB. About the adjustment layers: Adjustment layers are just solids. I am just trying to be resourceful. You do not need 5 different adjustment layers if you use one solid for all of them. Also when eventually changing scale of the project, you need to change one solid and all the adjustment layer solids will pick it up.

@1ne336 4 жыл бұрын
@@SilverwingVFX Thanks for answer, great trick with solids. But if for example you need to composite linear files with 8 bit files, if you dont set your color working space AE doesn't know how to linearize low dynamic range files with "gamma" encoded. (unless you put color profile converter effect on each file) It's simply not avalible on footage panel. But you can assign profiles to files most of the time when you set up color space and do linear compositing operations with 8 bit files such as blurs, dof, glow. It will give you a different result even if you ticked blend gamma 1.0. And what i've noticed even with linear files like exr you will get a little bit different composite if you leave it just to assume 2.2 and if you set sRGB and linearize it. I think it uses HDR values more correcrtly. Once again great video.

@@1ne336 Hi and thank you very much for your insight. That could answer one of my questions that I have during the video why comping light layers over each other looks slightly different. I think I will use the sRGB profile with linearized color space in the future. Thanks for sharing those insights with me! Usually I am working in FullCG workflows where everything I am comping was 32bit. That might explain why I did not encounter any big differences "Blend Colors Using 1.0 Gamma" and adding a proper color profile with linearized workspace.
