I'm trying to load an .flt file and then assign a cliptexture to it. The model I'm loading references a texture with an extension that it doesn't know how to load. From what I'm seeing, I suspect that maybe since the texture doesn't get loaded, the .flt loader throws out all the tex coords, so the geosets are only left with vertex coords and normals.
I can assign a regular texture to the model by creating a new geostate that loads a texture and uses pfTexGen to make new texture coords. The texture won't show up if I don't use pfTexGen.
I try to replace that texture with a cliptexture, but my app crashes like so:

This reminded me of a message that I got from Paolo a while ago that said this:

My gstate already points to my cliptexture when I assign it, but maybe the geoset doesn't have any tex coords. Does this make sense, or am I barking up the wrong tree?
