Finally, this is how the meshes look in Wings3D.  They're pretty clean, but you can see how the extreme Gollum morph futzed up the fragile relationship between Antonia_1.2's face and brow layers.  I have another, rather involved, process that I'm going to integrate for that sort of correction.

Also note that the areas outside of the marker ranges (such as the scalp and underjaw) still need some kind of handling.  The process is protecting the weldline vertices, but still needs various other refinements.  I'm thinking of adding an Adjustments" tab just for the cleanup tools.

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.
