I thought auto-balance was intended to be used after a pose was finalized, as kind of a correction for impossible poses.  That's how I'vew tried to use it, in the past.  I don't recall that the results were so bad, but then my posing skills are pretty bad anyway, so maybe it could only improve things for me....

I'm gonna have to try using it while posing now, however....

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.
