But that’s just a convenience not a need. That’s basically rendering in ACES.Īrnold for example allows feeding whatever to the renderer, define a color space (IDT) in the texture node so it auto converts to working space (Rendering Space in Preferences) with OCIO. What you actually need is feed ACEScg textures and apply an ACES sRGB viewer transform. I saw your thread in the mail bulletin, surprised no one answered yet. Is sRGB and Rec-709 virtually interchangeable? I ask this because in this post by Christophe Brejon, he described a process for making a LUT to be used in Substance painter. Anyway, if my final goal is to display my work on the internet or sRGB, how should I convert the ACEScg (or whatever format is used to grade…Ive heard of ACEScc but have no idea what the difference is) to be seen back correctly in sRGB? Can I do the grading in NUKE? just a thought to save a step. What format should you export out of NUKE then to go to the color grading stage. Next, from what I found, it seems like most people do their color grading in Resolve. I understand that Arnold works with ACES fully but I don’t really want to learn a different render engine… I have seen some posts on here discussing different workflows and some were saying that they would render in sRGB EXR (basically do everything the same way they used to work before aces, and then convert the render to ACEScg in NUKE to do any compositing. Do I have to CONVERT all my textures to ACEScg in NUKE before bringing into MAYA or do I NOT CONVERT because the rendering will be done in linear sRGB EXR anyways so it won’t matter. This topic has come up in other posts for similar render engines like Redshift and Octane but the “solution” is really just to use a LUT in the VFB after rendering.

I have gained great insight through Christophe Brejon’s posts and online book but I’m still wrapping my head around the whole thing.įirst off, I use Vray but it DOES NOT allow rendering in actual ACEScg as far as I know. I understand WHY I would want to use it but the technical part is getting me in a couple areas.

Hi all, I’m a student currently and am trying to understand exactly how to use ACES for my color space in CG.
