Grain in smoke

I am using a large scale smoke emitter from a moving truck. The truck goes pretty close to the camera, and there is considerable grain in the render. Any ideas how to fix this?

Is “use light cache” active in Phoenix render settings? If so, try turning it off or try to decrease it to 0.2 or lower.

I don’t see that option is it in the Volumetric settings? I am using Scanline renderer in 3dsMax BTW

Ah ok, then I don’t know. Haven’t used Phoenix with scanline.

Hey,

The Phoenix Light Cache is there for Scanline as well: Chaos Docs

This really sounds like your best bet. Additionally, please check if Probabilistic Shading is on and try to disable it from the Phoenix Atmosphere: Chaos Docs

Cheers!

Unchecking Probabilistic Shading did the trick. Thanks!

Yay! Glad it helped :slight_smile:
