I have managed to configure the iC7 Toon Shader to give excellent results, but generally the chief problem with the shader is that it delineates too many facial contours, marking up the face with an unpleasant appearance. *Note that this is true even when the Edge Width and Intensity are at a minimum.*

My request is for a mechanism to control how sensitive the shader is to facial contours. It needs to handle only the eyes, brows, nose, and mouth, and jaw, and stay out of the other flesh areas.

Maybe this could be implemented as a new map in the facial Texture settings?
