Brazil toon shading question

[sidewinder]

When using the Brazil toon shader in "gooch" mode, if I turn on "receive shadows", the shaded area gets really jagged edges. Does anyone have any idea on how to fix this?

I have attatched a picture for your viewing enjoyment.

what sort of shadows are they, raytraced, shadow mapped, etc?

Aside from changing the shadow type (and bias if it's a shadow map) I can't think why it would be doing this :/

[sidewinder]

It's ray-traced, with default settings. Shadow maps actually give a pretty cool look if you mess with the settings, but they end up making the gooch look too 3d and not very hand-drawn. I'd like to preserve that dark area that makes it look almost like multilevel paint.
