Hi Cage!

I know Modeler applications can alter the resolution of a mesh.  Do we have anything like this functions in Python; have you considered just injecting a  Low Res. Target with pixels, just to make the Resolutions even to start?  Then you may be able to rule out piggybackng, to a degree, if you use an Ocktree(Small areas at a time)

Speaking of Ocktrees, I think this approach  would be rather affective where you mention only comparing Eyelash to Eyelash, and Lip to Lip.  The drawback might be needing such custom detail at every figure.  But then again this is'nt something that could'nt be done with little patience.  I've already spent considerable time creating some, of these Groups in V3 figure's Head, for my magnet work  If you're interested let me know. I've those, and with any anticipation I'll draw more for Sydney, M2, JamesG2, and/or Kelvin?
