I may have found a joint parameter which doesn't handle as well as it might.  When "Swing" is used on the feet, the distortion seen in the attached image can result.

I'm not sure whether this is meant to be one of the "unrealistic posing" exceptions.  I suspect one should favor shin Twist over foot Swing, but the latter can be important for pose tweaking, like hand Twist or head rotations in addition to neck rotations.

Also, I'm glad you're feeling better SaintFox!  :D

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.
