I’m rendering a smoke animation and it seems to be pixelated despite experimenting with the settings below. I’ve added the .blend file and a video to show the effect I’m seeing after a very high quality render.
I’m happy with how the smoke looks, I just need to get rid of the grain/pixelated effect
I’ve been through the forums and used the following settings:
In smoke domain, divisions are set to 64, density at 0, temp diif at 0.1, dissolve (ticked)
-smoke adaptive domain turned off
-smoke high resolution turned on (divisions at 1, wavelet
-I’m using cycles render with the principled volume shader, everything is at default except the density which is keyframed
-When rendering I’m clamping the light at direct(8) indirect (6)
-All caustics turned off
-glossy to 0.05
-I tried the denoiser but couldn’t see a noticeable difference so turned it off.
-There is also a flame in the scene. I’ve left it in just in case it could be affecting something
I think this grain is caused by the cycles rather than the resolution of the smoke.
Can I ask you - is smoke and flame rendered separately from the rest of the scene? If so, you can blur a little ( about 8 pixels) - this looks OK on smoke, cos it’s kinda blurry anyway.
Also, there’s this button (below) that means that cycles puts it’s cycles grain in a different place on each frame, meaning that it acts more like film grain rather than a non-moving overlay.
