I have some overhead Spotlights in my scene, lighting the floor. Camera is looking straight down, craning downward as it it levels of to horizontal.
In all my render tests, I get these flashes of light… like out of focus sparkles. I have narrowed it down to GI render.
Turn GI off, and the flashes go away. I have tried with visible light in the Spotlights on and off. Noise in the light on and off. Makes no difference.
I really like the way my renders look in GI… but the render time to try to isolate and fix this issue is killing me. Anyone have any suggestions what might be causing this? What Parameters should I be focusing on to try and fix this?
I have attached a still with little pink arrows pointed to some of the light blobs. They only appear for a frame or two, then bounce to another part of the screen,
