I read Nerd's comment about Geometry Switching not being compatible with weight mapped cr2's, before I even made my original post. I think maybe you don't understand...

Geometry switching can work with any body part actor and as you must know there are many types of Poser "Figures", not just humanoid that are expected to bend. And surely you don't think it's only for hip body parts? ANY body part.

Architectural figures for instance. At the spin of a dial you can swap out multiple door types (or any "body part", e.g. rigged element)  that can have it's own unique mesh not dependent on matching vert order/count (as do morphs), including new UVs, materials, and morphs.

Or SamTherapy's Geometry Switching Daleks for instance (not a pelvis in sight there)

Or Kirwyn's original Kez figure that had multiple dialable outfits built into the figure

Or the Geometry Switching hands I built for the Missus figure I created

And many more examples, including things created by Anton Kisiel

The uses for the tech encompass much more than genitalia. And much more flexible and sophisticated than replace body part with prop.

Very old images of my Missus figure's Geometry Switching hands...

My point being that I think it would be a mistake to dump the tech, if it comes to that. Not all "figures" require weight mapping or unimesh. In fact the large percentage of cr2s you'll find dont...
