Controlling a Volume Light with a Field

Recommended Posts

I am trying to generate a field to control the light intensity of a volume light, and I'm having a little trouble figuring out how to go about it.  I started off trying to take over emission properties on a material, but that didn't seem to be getting me anywhere, so I switched to trying to directly control the light_intensity parameter on the light.  I know this should be possible, but the how is escaping me.  I can always control the intensity based on color values, by setting them so the magnitude is over 1, but that feels very hacky and hasn't returned the results I would like.  I want to be able to keep the color value and light intensity as independent as I can.  Obviously I know I can't make a black smoke glow brightly, but I should be able to have white smoke that is lit up by the colored lit up volume.
