And finally, sweet, sweet success (in that this is the actual Antonia with a pimple morph rather than a fixed high-res prop impersonating her):

The script is not fast yet, nor is it running inside Poser, but it's werking. Huzzah!

Next up:

- Bake down to all the intermediate subd levels (currently only the base and highest level are done).

- Test on some more interesting morphs.

- Do a first optimization round, focusing on things that likely still need to be done in the Poser version.

- Convert into a "manual" Poser workflow by implementing the required operations that Poser does not yet support natively as small Poser Python scripts.

- Work towards full "one-click" automation.

- More optimization.
