Thank you, mac. I tried the dial-a-prop. It changes the entire geometry for the item. In effect, the entire item is changed as a whole. I'm wondering, does that mean poser loads the entirety of each of the possible geometries into memory? Or does it only load the one geometry it needs for the current dialed item? I was hoping for a way to have common parts of the prop load and stay, with the changing part, err,well, changing. It'd be a great way to cut down on total file size, too - if it can be done.
