I tried to duplicate the above Falloff lighting in Shadertoy. I created a sphere method that returns a float distance and then created 3 spheres and each one used the corresponding falloff calculations. The green and blue ones look similar to yours, but the red is very different. My red one has a mostly black center, and the red density increases until the edge of the sphere. There is no falloff past the edge of the sphere. This is not a big deal, but I am just curious of the difference. Thanks.
