Here's an initial release for the posed chainprop script.  I'm still trying to work out a decent way to fix the misplaced links at tight corners.  The current approach can help in some cases, but it worsens the situation in others.  

Most of the options for the script are the same as those for either the chain-making script or the extrusion script.  I'll try to type up basic instructions soon.

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.
