aiToon Forcing a Line Tips?

[ebomke]

A question for the aiToon users in the house. Im wondering if anyone has a successful way of essentially forcing aiToon to generate a line in a certain portion of a model using a map/image/texture. The thought being that a map can easily be switched out and thus could generate different lines on a model.

My initial thoughts were to use a bump map to force the mesh into thinking there was a height difference and making a line. Here is an example of the result. You get this awful double looking line only using a thin bump. So a totally failure.

Any thoughts?

Reducing the angle_threshold will add more edges to the model.

Displacing the model will also create more edges. Example here.

Thanks for the reply Lee, however this isn't what I was looking for. Angle threshold will give you more lines overall on a surface material. You can use maps all day to remove lines from certain portions, but there doesn't seem to be a way to add a line in a specific placement every time.

Heres a great example. You have a character and you want to give them laugh lines without modeling or blend shaping geometric normals to distort the mesh. So you would want to force a line generation, but Im not sure how you would do it where it doesn't give you the doubled line like above where its drawing a line on both sides of the bump map.
