Ahh, but thanks! That's something I needed to know anyway because I made a noobish mistake and didn't have the chest part running between the pecs for the front legs, or the wing shoulders, so both were creating splits in the obj, because the whole, "children can't touch" thing... That was in the tut I'm watching, I just was negligent. So, if I change the shape of a group, and import the new obj, and use the setup room like you just described, to "transfer" my figure rig to this new obj... there probably won't be any issues? As long as the number of bones doesn't need to change or anything?
