Help with lighting?

So I have 2 seperate parts to my gun that I made and when put it in textured mode the bottom half is white like there is no light and the top half is normal. No matter where I put the light I can’t get the bottom half to look normal How do I fix this?

I’d bet that you have 2 materials on the gun - the textured part has the material with the texture assigned to it, and the other part has a different material. Look at your material slots,and if there is a second texture slot, get rid of it.

At any rate, it has nothing to do with lighting.

try flipping the normals of that bottom part
EDIT: ok that probably won’t work… a .blend would be nice

Agreed. Also check to see if you’ve got any doubles (w - remove doubles)
