I'd like to feed the skin texture into the bump input because i feel it makes it look better. this particular texture did not come with a indipendent image for bump but the idea would be the same. most of the complication comes from spearating the skin from the clothing. the clothing connects to difuse color, and the skin goes thru alternate difuse and i also removed the clothing from the specular and alt specular. when i tried using the math node at -1 it looked like it turned the image solid black so im not sure it is doing what i want.
