    What is mrao?

    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.

            Pretty much. The different terms refer to different uses of the same type of data.
