Proper Texturing Workflow for Unreal Engine

Thanks for this great thread ! There were a couple of similar topics on the forum in case you haven’t read them :

Utility-srgb-texture too dark

Hello everybody, I’m scratching my head around ACES and srgb texturs so I hope somebody can point me in the right direction. I’m using maya / arnold / Aces_1.0.3 / and megascan textures. I know it is normal that the textures get darker when you use the Utility-srgb-texture but still I have question on the consequences. I downloaded the ACEScg_ColorChecker2005.exr from AMPAS github. My understanding is that it would help me get the correct exposure for my lighting. So I loaded the checker w…

Linear-sRGB not behaving as expected

In theory one should be able to read in a linear EXR image with Utility-Linear-sRGB and thus have a linear file that was made using sRGB primaries display the same in ACES. So I would expect if I viewed an EXR in Nuke default, and viewed the same EXR in ACES, read in with Utility-Linear-sRGB that they would be identical. However as you can see below they look quite different. There is a notable shift in colors (the ACES going towards green) and the blacks are crushed. [ACESlinearProblem] You…

Mostly answered by @Thomas_Mansencal There is probably more stuff to read about albedos and such but I would have to dig deeper in the forum archives.
We are also trying to develop an open-source tool based on the Pointer’s Gamut to help artists to check their textures’ base colors (as a personal initiative, not ACES related). Maybe it could be helpful.
