the custom textures only affect what you see, not what other players see.
btw, there are some strange 256x1 pixel texture files, in each characters folder ( multyply and aditive i think they are called ) that have to do with the color of the flags and teleport orbs (??)
This is what you get when you add noise to Normals file. not how the sense of depth and bump is lost. ( also model is black and white )
