Attached Link: Problem with MAX Import / Bump Map

I tried to make an water like surface skin for a character in MAX2.5 . I imported the obj. file using the HABWARE tools. That works fine but if I apply any bump-map or bump-noise to the surface it does not work. When I render the picture I only get the siluette of the char, it's seems to have no surface at all. By the way, transparency with the character works fine.
