Just signed up there earlier today, so will look around for the tutorial. Lot's of other interesting stuff there as well. Actually got it to read two separate obj files, so next try going for all four replacement parts for the torso. Messes it up when/if you save it to a new cr2, so still missing something. Pretty sure I missed the bottom section. But at least it can just read them, so don't have to go back and import/place/replace them every time I change one piece. Bruce
