Hmm.  I've tried using the default settings and the 0.000125 you suggested, on one of the messy V3 results I'd been showing.

The processing took awhile, which I don't mind, if it's doing something.  Your process looks interesting, from the quick glance at the code and notes I took earlier.

After it ran through all its steps, though, it failed to clean up most of the mess, both times.  The worst areas were cleaned up, but many areas were skipped altogether.  The scalp, where the mesh density is lower and it's more susceptible to standard smoothing techniques, shrank significantly both times.

I notice that you've set both "Omit Welds" and "Omit Split Edges" as on by default.  First, the latter makes the former redundant.  Second, we don't know whether a prop of figure is being handled and I would consider checking the welds as default to be a potential unnecessary processing step, albeit one which won't take long.  Third, the split edges screening will block things like the edges of eyelashes, which can end up very messy with our process.  It's your choice, obviously, since you're doing this variant, but I would think that both of these should be set at the user's discretion.

Any idea why it isn't working for me?  Do you need images, or something?  I can put up the messy morph on my site and PM you the link, if you'd like to test that for development.

Edit:  The original Restore Detail cleans up the whole mess with very little shaping distortion, very quickly, with two passes with Threshold set at 0.1 and no other settings changed.
