Hi, I'm working on a movie now with large amount of 3d objects (particle simulator with 3d models as particles). My problem is that particles lighting is flickering breaking whole scene. Below are two zoomed frames. First is bad with some strange grain apears all the particles, next is clear.
I'm using 2(3) point light source and environment map to light particles.
In final render it looks like one of the light just randomly strobe. Any suggestions what is the reason of such behaviour?
