The intensity of the specular blob in objects affected by the light. At [code]0[/code], the light becomes a pure diffuse light. When not baking emission, this can be used to avoid unrealistic reflections when placing lights above an emissive surface.

Controls the distance attenuation function for omnilights.
A value of [code]0.0[/code] will maintain a constant brightness through most of the range, but smoothly attenuate the light at the edge of the range. Use a value of [code]2.0[/code] for physically accurate lights as it results in the proper inverse square attenutation.
