MR Contour shader, customising shaders

Dave Jones · November 15th, 2004

Hi, Having recently bought my Viz 2005 upgrade, ive been exploring mental ray alot recently to see what extra benifits i can gain from having it.

I've especially been using the contour shader, but the standard shader settings are very limiting, and it seems very difficult to tailor the results.

For example, when a contour is displayed due to angle changes on the surface, some conours show when you don't want them, and others don't show when you do, this preset seems impossible to change without actually editing the shader itself.

Also, i'm wondering if it is possible to have a semi-transparent object show contours through itself?

I know the best solution would be to use Finaltoon or Brazil rs, but i really want to get what i can out of mental ray. Can anybody help with regard to editing, and tweaking shaders for Mental Ray, or guide me to a good place for helpfiles and advice?
