there are a left and a right butt bumpmap,in what bodypart
do they correspond?

i am asking because there is no butt texture

Butts are tiny little blocks that are attached to glutes.

You can only really see them when your hips are dismembered. That's why there's no textures for them and there's no real reason to have bumpmap textures for them.

Also it's the only thing that's worth getting gradients for if you have full textures.

ok,so the answer is don't buy butt bumpmaps,thanks.
