Hey .. just making a bunch of sparkles (out of a point cloud with instanced point lights).

The falloff is very difficult to control (according to distance) .. with the default light controls; I'm wondering if anyone has a way to do the decay according to a distance based curve? (Animation or otherwise)

thanks!

There are some point cloud shader samples posted on odforce.
The surface gets shaded based on the distance to the points.
If you need to light a surface I'd take this.

If you need the light in a volume I guess you need to roll your own version of the ASAD light and plug a multiplier ramp/curve into the falloff calculation.
