Hi to all.
I’m having this problem and I’m not quite sure how to solve it.
Here’s what I’m talking about

Notice the lip area. The polygons are starting to misbehave. Whatever I do can’t bring them back to normal. Any amount of smoothing can’t do anything to cure the problem. So what can I do to solve this issue? Is it because this is not a closed polygon area? Do you think I should have built a few more polygons inside the head?
Thanks in advance.
