Materials are defined in the .obj file. You should be able to copy the head section from the original .obj and add it to your custom geometry to get the materials set the way you want them. Do a search for: g head that will get you the head section. Materials are set up as: usemtl tongue and the like. This will only work, if the head has not been modified in a way that adds/subtracts/modifies the vert order. -Trav
