do you know Quixel Suite? It's a great toolkit for photoshop and pbr texturing. It uses some kind of calibration profiles for various engines (like Unity and Unreal) as well as for other standards (like Disney GGX or Marmoset Toolbag).
As far as I know these profiles are for proper handling of things that are different between all these softwares (like normal map Y axis, tangent space, handling of gamma corrected vs. linear values) as well as deciding the types of maps that are exported.
So I wondered which profile would be best suited for exporting to Sketchfab.
Could anyone help me with that?
Or maybe we (the community) can do some research of which profile is best suited
Thanks in advance
