Funny morphs with 3DMeNow/PeopleMaker

[vmerget]

I'm using the following process to make .vzf files from 3DMeNow:

- Save morphed faces from 3DMeNow as a set of .wrl files
(Subdivision Iterations = 1)
- Use 3ds max 5 to convert the files from VRML 1.0 to 2.0
(Bitmap URL turned off)
- Open PeopleMaker on the "baseline" .wrl file
- Flip the polygon order
- Use File->Open->Create Morph and Tools->Generate Morph
Target to convert the .wrl files into morph targets.
- Autoscale the head, fix the neck vertices, and save the .vzf.

The resulting .vzf works, but it has some funny artifacts, even when I restrict the morph percentage to a number from 0 to 1.0. For example, apply a smile might cause a polygon to grow out of the cheek. The original 3DMeNow morph didn't have that funny polygon, so something must have gone wrong in the translation.

Any I doing something wrong? Any ideas?
