>>1744142>>1744143Hair bits do the trick. For eyeliner at least. If you're like me and make sequences/modify character poses a lot, it's really annoying to work with because most of the hairpieces either can't get small enough to fit to the mouth, or they simply won't match up to a given mouth shape.
Though I guess that's only for smaller mouth sizes. The easy way out is to just construct the entire mouth out of hair parts.
