" Hmmm, if you save as a .car, open it in Carrara and export as .obj with Materials turned off, the file size is pretty close to the original." I just tried that work flow for my little project but unfortunately it didn't work. Scaling and orientation problems resulted and the morphs wouldn't load. It's a major problem for me and I'm sure others. Hex is great but there will be a lot of things I can't do with it until this is fixed.
