Hi,

is there any chance to tell POV-Ray that a light-source only has to be
considered, if the distance between light-source and the point where a ray hits
an object is not bigger than R?

If have a scene with hundreds of light-sources which slows down rendering speed.
Due to a high fade_power, each light-source only shows a visual effect on
objects very close to this light-source, but of course also causes calculations
for distant objects.

Thank you!
