Running Carrara 7...

I have the weirdest problem. I'm creating some Poser content and want to do some test rendering in Carrara. First I made a pair of pants for Vicky and rigged them with bones in Poser. I then added the pants to my Carrara scene (pants being a posable figure now). Everything looks absolutely swell, the textures come out just perfect and everything.

Then I head back to Poser and add some morphs to my pants, thus creating a new character file (.cr2) and a new morph file (.pmd). I add the new version to my Carrara scene. But now it just seems like my model isn't UV mapped anymore. The default render behaviour in Carrara when you add texture to a non UV mapped model is to show some sort of base color of the texture file. And this is exactly what happens.

And this weirds me out, both figures uses the exact same .obj file. And from what I know the UV maps are stored in the .obj files and nowhere else. To sum it up, this is what happens...

pants1.cr2 + pants1.pmd + **pants.obj **= Working textures and UV maps
pants2.cr2 + pants2.pmd + pants.obj = UV map doesnt work

The UV maps are intact when I import pants.obj as mesh to the scene so there can't really be anything wrong with the model. This problem only occurs when I add them as Poser content to the scene. And the funny thing is that I can have both pants1 and pants2 in the scene at the same time, the textures work on the first one but still not on the second. And they're using the same pants.obj file.

Exactly what is going on here? What am I doing wrong?
