Im trying to make a halo3 assault rifle, ive got the model done but it keeps acting weird ingame...
No matter what i do with the shaders and bitmaps it always has these problems:
It either goes all weird like this: (3ds max also does this when i have hardware shading turned on)

or it has weird random colour differences like this: (mainly on the top of the ar and on the grip)
