don't light background just like Cycles does.

does cycles actually have this fallof? if not just use a step function.

l_vector is not normalized. so i'm guessing the 1.5 factors are not correct.

Normalized the light_vector

Best result I got with

float light_input = smoothstep(1.5, -1.5, -dot(N, l_vector.xyz));

But it will leave artifacts near edges.
