Quote - I saved a figure with and without animatable and the actor looked totally different in cr2.

What do you mean?  Was the animated origin formatting different somehow from that in the Alien Andy example, or were your two .cr2 files different internally from one another? 

I'm trying to make sense of Poser's internal handling of animatable origins and weight map assignment, for the weight injection pose scripts.  I'd be interested in knowing about any oddities you've discovered.  It could be useful to understand how Poser assigns the internal numbers used to identify weightMap listings, if any patterns emerge.

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.
