Quote - Can the update be applied to an already weight-mapped figure?  I spent like two days transferring rig to the first one ;)

Jeepers, you must have some mega-souped up V4 figures!  :scared:

I believe the script should be able to do what you're asking, but some rencent posts seem to suggest that morph dial settings may become confused for some users.  Vestmann has a solution posted above on this page which might help you.  If there's trouble, I will try to fix the script to meet your needs if you can report the trouble and what steps you took when encountering that trouble.  (I'll be out for a day or two, starting tomorrow, but I will do my best to fix the script if it needs to be fixed, as soon as I'm back at a computer.)

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.
