You might be able to put a set of spheres in a line and use something like shader ops to get it to produce the disks in line from the source to the edge of the camera. I think it would be easier to take on the two light approach. For the animation aspect of it, you could group the two lights, put the hotpoint of the group at the center of the main light and add the "point at" behavior of the group to point at the camera. That way the "flare" light is always in line with the source light as the camera moves. For other post rendering effects, I've used a spot light set at 1 degree angle and pointed them at the camera. This removes the light the "effect" light is introducing into the scene because it's only shining on the camera. I usually do this in combination with a bulb light that has to be behind something. Seems to work fine. -Kix
