What is the difference between sheen.ktx2 and diffuse.ktx2 #8
Description
Hello
Notice that we have a separate ktx2 image for sheen on each environment map. Is there any difference between the sheen version and other one for the same environment map?
I thought all of them are the cubmap version of the HDR environment map, with mipmap level matching to different roughness.
Sorry for this newbie question. Just want to understand the sheen extension better.
Thank you
