Quick Smoke Causing Grainy Renders I was messing around a bit with Blender 2.79, and what i found was when i was doing smoke simulations, the renders turned out really grainy with a lot of noise (kind of like scattered pixels around the smoke) in the simulation its self. I never really came across this problem till now, maybe there's something that I'm missing? I attached an image below, I hope you know what I'm talking about. :)




Thanks
Okay, so i found the problem i had if anyone interested... it had to do with my lighting. i guess for smoke simulations you cant use planes with a emmision node property. i had to use actual lamps or sun lights to avoid noise, but i still cant get it around my head how that works.

Thanks.
