I have a very similar problem now.

one of my models without shaders blends the colormap with the normalmap, both in MED's model viewer and runtime after ent_create, but don't know why, other models are fine... textures can be outer or inner, does not matter. 24b tga.


EDIT: it happened when imported again from FBX2010. I had an earlier import, maybe I used another format at that time, but now adding the normal map just works. strange...
