Well, I (and the whole supcom community), we are having some BIG problems with the beta ex- and importer for blender, it messes up the textures and animations, mirrors the UVs and so on.
So, we are looking for a good python scripter who can fix it for us! This would be really great, you would make many hundreds of supcom modders using blender happy!
