Testing multiple smoothing passes.  One pass is on the left, ten passes on the right.  More of the irregularities are gone, but there's still the "bias" in the head area.  The remaining sharp transitions between polygons seem to be due to the coverage preservation.  There's a slight amount of shrinkage in some rings, particularly in the shoulder area, which I think I can screen out by rearranging the smoothing process a bit.

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.
