On the right, this shows ten passes of Wings smoothing, to illustrate the differences in the smoothing techniques in use.  The Wings smoothing has averaged all vertex relationships, taking the shape further away from what we want.

On the left, ten passes of the restore detail script posted at the top of the thread.  We've come closer, with each pass, to the original vertex relationships.  The mesh becomes cleaner, without losing altogether the shaping of the morph.

Again, script settings for ten passes are shown.

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.
