Hmm.  I wonder if your inclusion of the figure section is making a difference.  I'll try that.  I think a good test would involve replacement with a geometry which needs to be welded.  When I try to insert intensified buttock geometries, which will be welded, as alternates, Poser gets mixed up.

BTW, what's the difference between 

storageOffset 0 0 0

and 

storageOffset 0 0.3487 0

?

Could that make a difference when applying one of these poses?

Interesting.

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.
