How is Python reporting the situation?  I don't recall whether it reports any and all weldGoal actors or just proper parent-child situations.

I don't think I've seen working sibling welds before.  I'm pretty sure that was the case I encountered, in which some vertices simply wouldn't weld.  :unsure:  It is surprising to see something like this now present in one of SM's own figures.

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.
