Posted this in the general discussion forum, was advised I'd get a better response from the mod forum.

I've just started up another game with a new character (fourth character it must be), using the alternate start mod to begin in a cave, and have spent ages on character creation as usual, the face generation part in particular. One thing I've noticed in the past with face generation, and I'm noticing it now too, is this issue with what look like the sides of the face being pulled down by invisible weights. It's most noticeable when in sneak mode, while standing normally the offending polygons jut out a little from the sides of the face. It happens along either side of the jawline, towards the back of the neck. While in face generation, it's rather tricky to reduce so that it doesn't happen at all (it's like the face is 'bubbling' in these spots).

A screenshot of my character in sneak mode where the issue is most pronounced:

A screenshot of the inventory menu, where you can see the 'bubbling' I was referring to (visible on the right side of the character's face - our left):

Using Wyre Bash, the mods that control facial meshes are TNR All Races Final, MaleBodyReplacerV4, and RTFemaleReplacerV12. My load order has the body replacers towards the very end, and the program does not show there are any conflicts. Anything loaded after does not mess with character models, and there are no conflict warnings for them either.

I've also downloaded BOSS and it has reordered my load list (with FCOM in there, it was rather gruelling setting it all up), and while there were no conflicts indicated by Wyre Bash, the new order also doesn't list any conflicts. I also happened to find a topic on Skyrim with a screenshot of an Oblivion Khajit using similar body mods (likely the same versions that I am), and the same bubbling/jagged edge issue is there too. It certainly isn't game-breaking, and isn't too noticeable either.
