to assign more than one texture to an entity just leave the line open like so...
;visualinfo
textured = [LEAVE THIS BLANK]
effect = effectbank\bumpent\bumpent.fx
castshadow = 1
Then make sure that the textures are in the same file as the fpe and .x file.
If part of the entity is textured and not the other, then you will need to locate the right texture or combine textures.
When you combine the textures you will need to make sure the model is unwrapped accordingly.
Good luck. If you cannot get it to work post the model and textures or send me an email. We'll get it for you.
