"Oh, and adp001 was correct, I had the inner mouth on a different scatter group. Also fixed here."

Didn't stop the glowing?

The scatter group fix isn't perfect. I still see the discoloration artifacts in my sss renders even with multiple obsessive scatter groups. Bagginsbill suggested you only need a few for the fix. Lips (if applicable) from the face and mouth interior materials groups. You most commonly see it occuring on the mouth, nose, and fingers. The only real fix is higher scatter scale settings. 1.3 and above is what I use.

Probably not worth mentioning. Actually, definitely not worth mentioning in this instance. But there it is.
