I am looking for a way to control the distance that Cycles emission shader can affect another object in a scene. I am aware of the Light Falloff node, however it does not have a distance control.
What I want is the distance parameter for a light like we have in Blender Internal. In Blender Internal I can set the distance for a light and no light will travel beyond that distance.
Does anyone have a node setup for Cycles that can emulate the Blender Internal lamp distance effect?
