I am working with the curve modifier for the face of a character I'm making. I'd like to be able to curve the mouth to make facial expressions. But I can't get the sides of the mouth to come inwards, it just acts like the curve vertex has moved vertically. I can get the lips to move up and down, but not sideways.
Any help appreciated. Thx.
Update: Lets suppose I wanted to be able to make a face like the one made below. This is what i mean by I want the sides of the mouth to come inwards. By making the sides of the mouth closer to one another, with the curve. (I did not use the curve in this example)
