Environment fog cause artifacts(Vray3.6.01)

[Shiyan lin]

1. I don't know is it a known issue,but I render artifacts when chosing ?Affect by selected light ? option,just check the effect channel attached below


2.Sometimes, affect by selected light doesn't work,just look at the atmosphere channel attached,it shows fog affect interior objects, I only suppose to let light outside affect bathtub

Hi Shiyan lin,

The 'Affected by' option is supposed to break the connection between a light source (the non-selected one) and the volumetric effect.
This means that the fog will not become invisible in places where it is not illuminated but will instead appear dark.

It's actually hard for me to determine what's going on in the image attached. It might still be incorrect.
Is it possible for you to share a simple scene that I can test?

Thanks in advance,
Konstantin
