Grainy lights
March 25, 2015, 04:24:37 AM
Hello Everyone,
I have a small problem with light sources. I am working on a night scene and I would like to have a few light sources here and there. Unfortunately when I put them in place, the area around the source gets awfully grainy (like it was snowing or something.) The lights are about three meters above the ground's surface.
When I increased atmo samples and turned off "Glow in atmosphere" setting it got better but it still looks grainy.
I remember that I managed to solve this in the past, but please, be so kind and remind me how it's done.

Generally speaking disabling the glow and/or increasing Atmosphere Samples are the best approaches. If your scene works well with Defer Atmosphere, that will also help a good deal, but may raise render times. Alternatively you could consider this trick of switching a cloud layer for your atmosphere (especially for a night scene, where atmosphere is less important):
