Sorry, I'm at work right now, so I can't post an image, I will do so when I get home tonight.

But, yes MarkBremmer that is the effect I'm looking for.  If you imagine in you r image, what I'm getting is no texture on the side in shadow.  I am a newbie with Carrara for the most part, but I think what CaptainJack1 mentioned makes some sense, the part about the multiplier in the shader.  I'm so used to Poser's shader style, so I have a lot to learn in Carrara admittedly.

I'll post an image later.  What I'm aiming for in the final is an animation of a spaceship flying through space with the controls all lit up, providing some interest to the cockpit.
