I have a scene where I need to add many sources of small lights. Is there a method that is more efficient than others?
Option A: Use many instanced area lights.
Option B: Scatter my light emitting planes thru the scene and use a mesh light. All connected together (or into color groups)
Option C: ??
Increasing cutoff threshold will help. Anything else?
Update: Vray area lights worked very well. I have 1300 lights in the scene and probably at least 800 on screen/casting range. No real dramatically unexpected performance hit. Scene looks really nice. Thanks
