Changing a character's base body...need help

[badmotivator]

I'm redoing the Disciple and I've run into a snag. Got his new head, a modification of Dustil's, but I want to change his body so that it's the Republic Soldier's with it's own unique skin. I've got the body set up to work with him (modified the appearance.2da file), but I can't seem to figure out how to get a texture map on it; it keeps coming up all white. Anyone here that can point me in the right direction? Thanks in advance...
