I noticed something in the Standard shader that surprised me. The Metallic Map uses the R channel for metalness, A for gloss/smoothness, and G and B channels are ignored.
But both Height and Occlusion both use the G channel only, and ignore RBA.
Would it make sense to change one of those to B so that a map can be packed as such:
It seems that having both Occlusion and Height on G is a bit of a waste because it requires them to be individual textures.
If there something I am missing as to why both are on G, or was one supposed to B from the get go?
