I am using some area lights to illuminate the interior of a cabinet:
However I want to attenuate the lights so their area of influence is much smaller. Like this reference image:
I've tried playing around with the light falloff node but can't get it to do what I want.
Any help at all is greatly appreciated.
Getting much closer by trying what Rich Sedman linked here. I changed the light attenuation to cubic by dividing the light falloff by the ray length. It's still not where I want it, but progress nonetheless.
Looking a lot better, but now I'm getting really bright fringing close to the light sources. I am immensely frustrated that it's so difficult to match VRayLight settings in Cycles. I feel like VRay's emission "algorithm" looks much more natural then cycles.
