What I mean by duplicate CR@ is just that. I make a copy of the original CR2 and edit it so that it loaded the newly morphed complete figure. I then click on each body part and export the body part as a morph target to be loaded back to the original figure. It's much easier to make morphs match if you morph the entire figure in zbrush and not just one body part at a time.

Say you want to make Full Body Morphs for Dork. It's easier to load the entire figure OBJ into zbrush to morph it than it is to load one body part at a time and get the morphs to line up properly when reloaded.
