improvement to remove noise of volume light.

[flat]

With EnviromentFog and Small V-RayLight[Disc or Rectangle], it is difficult to remove noise when bucket rendering.

Raising max subdivs of image sampler to 70 will also produce noise. and Very slow rendering.
and Flickering will occur in animation.

We expect improvement to remove noise of volume light.

Shouldn't increasing your min shading rate help with that.

Thanks Gavin

Although raising Min shading rate improves somewhat, it does not become a fundamental solution.
(Increasing Min shading rate to 20 ~ 50 is probably not recommended.)

Perhaps there is still no good solution for current V-Ray.

Yeah, I seam to remember the last time I used it, was still in 3.5 last year and ended up having to do it as a separate render with black objects so the min shading wasn't affecting everything else.

No comment from Chaos?
We look forward to future improvements

we hab similar issues with noise near the lightsource.
don't remember where but i saw somebody using a vrayscattervolume material instad of the environment fog.
this is working great with much less noise.
you just have to place your camera outside this volume to get this working.
