Azman, I have fast interaction on, but no luck there.

Neostrider, I am using toon shaders. And I'm creating pfxToonOutlines for all of my geometry. It's just that I'm converting them to polys, just because I think it looks better. But, the layered shader idea sounds intriguing. Care to expound upon that? And sorry for any confusion my original question may have caused, but no, I'm not confused about how to turn a layer's visibility on and off. I already know about the layer display options. I'm not that much of a noob! :p
