Thank you for the video, I saw it recently and I simply wanted to roll down all the cases which we may have to deal with in Maya with Arnold, maybe correcting one or two of the ones you mentioned in your video: For linear images such as EXR and HDRI, we use as IDT in Arnold: Utility-Linear-sRGB For 8-16 color based images such as color and Albedo and Most textures you download from the internet are going to be in the sRGB color space, which you’ll see in OCIO as: “Utility - sRGB - Texture”. For gray images or Utilities such as Metallic, Bumb, Displacement, Normal we use: Utility-Raw or in another reference, we consider them linear images and use: Utility-linear-sRGB For light maps and Mattes, we use: Utility-Rec 709- Camera For images which are already converted to AcesCG, we use AcesCG I hope that makes sense

It does make sense and seems right, but still the “Utility - sRGB - Texture” color shift the internet textures a Lot. And it seems that in Maya 2023 they simplified all of the options to just: "sRGB" for the color and 8bit textures "Scene linear rec709" for HDRIs "RAW" for the utility textures The sRGB still color shifts the textures. And it now have a "Invert View" option to make them look corect, but give you a warning, and seems to be out of purpose. EDIT: the purpose of making them darker is to allow you to give the light stronger values, as the Aces color system gives "more headroom" in the highlighs. It is a bit strange, the colors do end up looking more saturated but maytbe it is it's current intent, and maybe if this colorspace is more adopted we may have less problem in the use of textures.

work linear. but instead of using SRGB to interpret your render view and texture import , you choose ACES. problem comes when adding textures. no sweat. convert them from SRGB to ACES and all will look nice and dandy. save Renders linear with no color profile. floating point exr is best. import to AE/Nuke /whateverprogram. add from LINEAR to ACES conversion and comp it. output SRGB. I think it works like this.

One question - why did you pick the utility-sRGB-texture for your color picking change in your config - when you used this picker and changed the color/value of your walls?

Is there noticable difference here or will this get you into the ball park for correct values and colors? Using the utility-sRGB-texture vs utility-Linear-Rec.2020. THX

Output - sRGB is used when you want to preserve brand colors and images as you see them online, he should have used this on his movie posters, because using Utility - sRGB -Texture he damanged the brand colors. There are however dangers with Output - sRGB, because 1.0/1.0/1.0 on a movie poster will be 16.3/16.3/16.3 in acesCG if you used Output - sRGB. So you have the right "look" but the colors are wack and will shoot an unnatural amount of rays back into the scene. So what you actually need to do is split the rays, have camera see Output - sRGB, but indirect rays use Utility, sRGB - Texture. Well thats my opinion anyway
