*"As the geometries are different, perhaps this is related to the morphs for the original geometry no longer working when the number of vertices changes."

*When I've been using this for the genswap hip I've been replacing the hip with a geometry which differs a great deal from the original, with bend on, in Poser 5.  I've been combining the swap pose with an INJ pose, so the deltas and geometry change at the same time.  So far it works nicely (in P5), but only for the hip.   I'll hopefully have these files up on my site in a few days. 

THe MultiHair on my site uses this swap method, with bend on and very different geometries.  It also uses combined INJ in the poses.  None of the geometry elements would be welded to another body part, however, so the bend settings may not be impacting anything in this instance.

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.
