There is a history of special versions of some figures, intended specifically for the Walk Designer, IIRC.  Perhaps that's what is needed for Antonia?  A special WD build?  Assuming that's something we can even work out.  Does the WD require special data files for the figure rigging?  I'm a WD ignoramus, sadly.    Cage is not one of the Twelve Poser Animators.  :lol:

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.
