Hi. Mrao means ambient occlusion or rougness?
It’s hard to say, but it could mean “Metalness-Roughness-Ambient Occlusion.” Are the red, green and blue channels packed with different looking greyscale textures?
Metalness, Roughness, AO packed in order in the R, G, and B channels. Usually because the green channel in DXT1 compression gives you one additional bit of information(5, 6, 5 respectively), but it’s not really noticeable in my experience.
Mask-Roughness-Ambient Occlusion. Cool. Thanks
Also, is Displacement, Bump and Height same thing?
Pretty much. The different terms refer to different uses of the same type of data.
