That's the best explanation I've seen yet of light_ source output, thank
you. My question is, what does fade_power do?
If I have a light_source with <7.5,5,1> it's output is white, however using
a light_source of <.75,.5,.1> with a fade_power of 10 & fade_distance >
distance_to_camera, it's output still looks amber.
