It is designed to be used with any figure at all, but there are many things yet to finalize before I can start varying the heads along with the pics.  If I've done it right, one should be able to open a full Poser figure geometry and receive a morphed head as the result.  Proof of concept tests for those features have worked with simple test geometries, but I haven't reached the point of testing with a full figure geometry.

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
