intensity: intensity: Multiplier for the light intensity.
exposure: exposure: Exposure control for the multiplier.
invert: invert: When this is on, invert the multiplier. For instance, if we set the light filter’s intensity to 2, the final light’s intensity will be divided by (instead of multiplied by) the light filter’s intensity.
diffuse: diffuse: How much this light filter affects diffuse lighting.
specular: specular: How much this light filter affects specular lighting.
saturation: Saturation of the light before hitting the surface (0=greyscale,1=normal,>1=boosted colors).
