New Lighting Artifacts in Renderworks


I have started getting some odd rendering effects, the formerly smooth lighting patterns from some of my .IES driven Custom Light Objects have become kind of pointillist and weird like the forest breakup gobo I wish really existed. The down light object symbols in the hallway are the same as the ones in the dining room and living room, and in other renderings they looked correct. I have messed around with settings for awhile. This is Final Renderworks, 16 bounces, ambient occlusion 40%/1', ambient lighting is a mid gray at 30% which usually works, the levels on all the down lights is the same, 2000 lumens @ 100%.


Has anyone seen this before? What's the fix?

Double check that the light objects aren't intersecting the geometry of your ceiling/wall. I've seen this speckled effect happen when a light was exactly on the same plane as another object.
