heya; if you want to do some simple 'people with animal heads' type things, you can either... A: turn your human's head invisible and put an animal head on it (with the body turned invisible), then parent the animal to the human. (this method leaves a lot to be desired.) B: do the same thing in poser 4, but export an obj with the human body and the animal head (make sure the head is in place). then, edit the human's cr2 file to point to the new obj (save it as a new cr2). then it will be one integrated model. you wanna mess with animal paws... that's gonna be tricky. definitely need some higher powered 3d modelling tools for that.
