Glossiness Map Equivalent?




What’s the equivalent of glossiness map for Mesh Standard Material? This type of map is often included in texture sets: For instance, it’s a part of Poliigon default set:

As far as I’m concerned, a glossiness map is an inverted version of a roughness map. Although a roughness map is supported by Mesh Standard Material, it’s of different kind (green and brown).


MeshStandardMaterial uses only the green channel of a roughness map - it should work fine with a grayscale map, too, but this allows you to pack occlusion+roughness+metalness (RGB) into a single texture.


Should I invert a grayscale glossiness map to get a grayscale roughness map?


I think that’s all you need to do. Or even just set material.roughness = -1 maybe. :sweat_smile:
