It's looking like I'll be able to add a chain figure posing script, with animation and the same dynamics as the prop script, to the set.  So far the process is working out nicely.  That matrix math works a treat, once you get the hang of it.  :laugh:

I've added a feature which creates a path preview prop as you position the marker points, to clarify what's happening.  That seems to work nicely so far.  That will be in the posing script and will be added to the chain prop and tube extrusion scripts.  The tube script will also have the animation options added.

And maybe I'll see if I can build in an automatic catenary feature.  :lol:  I know a proper catenary is supposed to be mathematically elusive, but I think I still have code around which derives some sort of approximation....  :unsure:

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.
