View Full Version : Strange Volumetric Behavior

Hi all,

I found a strange thing happen when lighting a stage with 48 concert style spotlights this week. They are setup exactly the same as they were cloned after settings were confirmed. All have volumetrics on and when test rendering without raytrace on they show up perfectly.

I then turn on raytracing and about 18 of the lights don't render at all. The only thing that these have in common was some Intensity curves edited in the Graph Editor. I was experimenting with groupings and parenting lights to try and affect some properties with one change (it never did work and I tried several different methods - weird).

Other than this, all the lights appear to be identical. I am stumped! Ideas?
