I humbly request that one of Polycounts amazing artists make for us an example of a pbr character that shows of how to deal with all common character materials, and then make it available via the wiki for all to download and learn from.
PBR examples I have seen so far do not deal with skin, hair/fur or any other living material. Just metals, woods, plastics and stone.
For example a mutant guy/gal with spiky hair and a mullet, a normal skinned face, a crocodile skin left arm, an old man right arm, furred pants.
Cheers in advance
