Poser 9 should be able to transfer weight mapping, using the Setup Room or the Figure --> Copy Joint Zones from option.  However Poser 9 will not allow editing of weight maps using the joint editor tool.  That feature is unique to Poser Pro 2012.

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.
