environment fog and scene scale

[shadevfx]

Hello, we are using Vray environment fog to create volumetric shafts of light. The scenes were tracked in real world scale, so they are quite large. The env fog seems pretty angry at this and is rendering extremely grainy. If I create a dummy scene with a smaller overall scale, the lights render quite smoothly.

So, is there a workaround for this? I'm kind of surprised, as in general vray seems pretty happy when scenes are accurately sized.

It's a huge difference so I hope theres something I can do differently to solve the issue.

Thanks,
Bryan

Can you post a simple scene for this?

looks like user error/lack of experience. We got it sorted with the right amount of samples and fog density.

sorry for the false error.
