I've had some luck moving individual vertices with the Morph Brush, using the Pull tool with a small brush size and Magnitude reduced almost to zero. Another approach might be to use weight-mapped magnets. Paint the weights to affect only the desired vertices, then move the magnets using the dials or numeric inputs. That should allow more control.

I actually came in here prepared to muse about that Seinfeld episode where Jerry angers his girlfriend after imagining her navel could talk. I always assumed the talking navel was a sanitized version of an original story premise involving talking genitals. So. I guess I said that, now. Umm.

Okay, third answer. Talking genitals say, "If I ran the zoo, underpants would be worn on the head!"

Umm. Perhaps Cage should be done posting for today. Ahem.

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.
