Toon Vs Contour

[cmascari]

What are the differences between the toon material vs adding a contour attribute to a material?

Also, would love to see toon or contour be available with GPU rendering. Is this in the pipeline?

There is no difference.
The Contour material is just a Generic material with all its Layers removed and a Contour attribute added.

The way the Toon effect is implemented in V-Ray makes it hard to support on GPU.
Never the less we'll look into ways to make that happen at one point.
