Hmm.  Looking at the edited pose with the mirroring, it looks like the rotation order for the right foot is different.  I pasted in the whole actor blocks from a pose I saved out of Poser.  Poser saved the Antonia pose with a different rotation order.

Which may raise some questions.  Does the order of the rotation parameters in a pose affect anything?  Do the rotation orders in our Posette source poses match those of Antonia?  Possibly we can improve results by making sure the orders are correct for Antonia.  Some of the trouble we're seeing could be strange euler rotation problems because Poser's application or an ordered rotation is being foiled by incorrect poses.

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.
