Hmm.  I managed to inject everything, but Poser's preview screen grayed out on me and the cursor vanished.  I was able to save the altered figure to the libraries palette (without a visible cursor), but the scene file would not save - doing so resulted in a .pzz of 0 bytes.  So the process works, but it doesn't work, in this case.  Yet I receive no such errors with the hip.

I'll try another test with bend off.  Perhaps bend can be turned back on using a second pose and the problems can be circumvented....

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.
