1 minute of messing with the faceroom Ethnicity morphs, and a couple pokes with the morphing tool.

when cranking up ethnic morphs that narrow/widen the head, the faceroom can create a seam on the neck (i left it deliberately). this can be fixed in seconds with the morphing tool set to smooth.  same goes for any seams on the neck that result from combining any Alyson 2 head morphs with Anastasia.  knowing how to use the morphing tool will also allow you to use the slightly rough base Alyson morphs, and make morphs of your own.

 

quick starting tips for the morphing tool:

Morphing:
switch to the CREATE tab
change to Pull, Relative to Screen
Radius ~0.01 (raise it to affect a larger area)
Magnitude ~0.05  (lower numbers for less pull strength, higher for more)

Smoothing:
switch to the CREATE tab
change to Smooth, Relative to Surface
Radius ~0.01 (raise it to affect a larger area)
Magnitude ~0.30  (lower numbers for less smooth strength, higher for more)
