Hmm.  The question makes me think about geometry insertion poses.  I haven't tried to use them to replace or reset geometry for all actors in a figure by using the figureResFile line, but a default actor can be restored using a pose, by using figureResFile.

I would approach it by writing out a new .obj file and routing the figure to use that .obj as its geometry base.

There's a geometry insertion pose script in this thread....

I'm rushing to avoid being kicked offline by AOL, and I fear I haven't explained well....  :(

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.
