Volumetric Noise/fireflies

[Mats]

Hi.

I am having trouble cleaning up this scene.
I just started out using Corona so might be some beginner mistake i am doing.

I have tried to leave the render on over the night. (1800 passes)
But its still not clean. The denoiser makes the problem a bit better, but does not solve the issue.

Any ideas?

It would be nice to know your render settings, you could try increasing the Light samples Multiplier and lowering your Max-sample Intensity. Also try pathtracing/pathtracing just to see. What de-noising you are using?

Thanks for the tips.

I did some digging myself and found someone talking about bump maps and other lowfrequency noise could make fireflies like that.
So i tried removing the bumpmap from the shader - And that seems to have made it better, i think if i leave it on over the night now it will clean up.

But again... i would like to have the bump in the shader, so i will try play around with the settings you posted. thank you :)
