I have recently been using Substance Painter to create textures to be used in an ACES workflow, however Painter does not currently have ACES texture support - colour textures are exported as sRGB “gamma(~2.2)”. However, I am using ACES LUTs in the render view, to match what I will get when I bring the textures into the production renderer. Therefore, to get a match to my Painter viewport, I am exporting the textures, then linearising them in Nuke using the “gamma(~2.2)” transform, and then finally saving as ACEScg - kind of emulating an ACES workflow.
This workflow gives me a perfect match in the production renderer to what I’m seeing in the Painter viewport, and allows me to work with the exact same colour values as I would in an ACES package such as Mari, which is great as it means I can switch between the two packages seamlessly.
My question; is there anything wrong with doing this? I.e is there some caveat that I’m missing? So far I haven’t bumped into any issues but I am curious as I understand this is probably not the correct way to do things.
