I've been doing a lot of Antonia pose-testing, although perhaps not vigorously.  :lol:  The rig looks pretty good to me, aside from cases where extreme settings are used (thigh bend > 80-90 degrees) or unrealistic bending is applied ("Swing" used with forearms or shins).  Or when scaling is in use.

The hands do slightly odd things if "UpDown" is applied on thumb1.  But WW doesn't process hand parts, so that probably needn't be a concern now, if at all.  (Does thumb1 UpDown fit into the class of "unrealistic bending", along with forearm & shin swing?)

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.
