Using the “wire deform” method listed on the link below, I can get the curve to “flow” through the curve. In other words, the movement of the influenced vertices are only through the U&V of the curve.

But what do you do if you want to translate the vertices outward. For example, move the bottom of the lips in a protruding fashio? How do you make the “wire deform” method listed on the link work?
