You will also have troubles using 2 charatures of the same model where different morphs have been applied to each(in my case DaCort's Naga & Echidna where they share the same Geometry file). In an earlier thread I learned that I can make a copy of the Geometry file with a new name then edit one of the CR2s to point to the 'renamed' OBJ file. The same technique was discussed for CR2 props as well, like putting multiple motorcycles into a single scene. A little work, but it solves the problem.
