Underscores it is, then.  And you're right about the Laplace.  I didn't grasp the fact that averaging is going to have to be a part of the smoothing process, probably in any method, until I worked out the Wings tighten method.  Which ends up being almost identical to the Laplace....

Handling seams for UV transfer is tricky.  There's no built-in frame of reference, and PoserPython offers no tools for splitting or welding texvertices.  So I've had to start by building a series of functions to create a copy mesh using the Poser Numeric array geometry creation methods.  So far so good, although I have to test this for speed.  It looks like a feasible seams handling method may need to do a 2d in-bouonds check of target UVs against source UVs.  But I'm still muddling through that....

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.
