the textures are brilliant ! Awesome work all around. I'm curious, were you using any photo textures at all to paint the diffuse, or is it all gradients and layering of painted details ?
damn ! all your materials and textures look so spot on. I think I remember seeing that RAD scanned materials for character costumes, did you go through some of the same process for non character related materials ? And were you only scanning diffuse/albedo or other channels as well (height, spec, gloss, etc.) ?
