Quote - I can't swear to this without checking, but I think some aspects of the way WD handles the hip are hard coded into the WD.

Looking at one of the WD poses, I see that the Hip actor has keyframed translations.  This may mean that the "in place" Hip translations are present in the poses, in which case an alternate set of Antonia WD files might help.

Where real problems would come up is when a walk path is applied, I suspect.  That's pretty definitely hard-coded, so we'd need a Python script, there.

There could be issues with distributing the existing walk designer poses.  Something like odf's renaming script could be distributed, though, to create Antonia-friendly copies with new names to avoid overwriting anything.

The resulting files still wouldn't be properly calibrated for Antonia's joint setup or angles of limbs, but they might solve the basic translation problems.

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.
