Additionally, it would be great if there would be characters with well made maps, something like an usable bump map , a diffuse map without burned-in speculars and shadows and a specular map which makes sense. In nearly all products, the diffuse map is much to uniform to resemble skin, the bump map is some kind of desaturated diffuse.

Are there characters with working maps out there?
