SDK: Shade pixels that are not illuminated by lights?

Hi,

I again have a SDK question.. :slight_smile:

I create a sphere and place an Omni Light beside it.. when I now hit render (with my shader assigned to the sphere), the parts at the backside of the sphere are black.

But I am ignoring any lightColor in my eval() function.. so, how can I make a shader that’s ignoring any light..?

Thanks~
Aya
