This should definitely go to the SPF forum, since that's where this kind of discussion is supposed to take place. This isn't vital information so don't feel bad about it, one of the mods will probably move this thread there soon.
I think the black is probably a shader problem. In the comments
here they mention that animation is done in a shader. I'm not sure what it needs to work properly - perhaps a rigged model, perhaps the correct normal maps, perhaps something else altogether. Any way, try using a different shader and see if that works any better.
I don't know the specifics, but IIRC it goes something like this:
CubemapObjChar - used for the rigged and animated characters
CubemapObj - all static objects, Obj at the end means it uses Object-based normals instead of Tangent-based ones
Cubemap - IIRC, this is the one that uses Tangent-based normals
If you don't know the difference between Object and Tangent normals, when you open the image in Photoshop or IrfanView or whatever (you might need to download DDS plugins first, Photoshop plugins available from NVidia), if it's a spectrum of colors on black it object-based:

and if it's cyan and magenta on light blueish/pinkish color it's tangent-based.
