Environment Fog not Rendering

[dphorvath]

Hi Folks, I hope this is an easy one, but I've spent 8 or more hours on trying to figure this out.
Up until the last couple releases of Vray for Revit I've had great success and produced many renderings.
Now I have downloaded 3.60.01 and tonite downloaded 3.60.02 in hopes that a bug was fixed.
My problem is that my environment fog seems to be there during the light cache stage of making the rendering, but then once light cache is done calculating, the fog goes away when the final rendered image is being prepared. I've messed around with so many settings that I've exhausted myself and frustrated.
Any ideas out there for why my fog is disappearing during the render creation? This didn't happen to me with prior releases of Vray for Revit, this is new, so I'm hypothesizing that fog is working a bit differently in these latest updates, or some other setting impacting the fog settings. I'm really hoping its just a toggle button or something obvious, so I wont be offended if a quick easy fix was posted in reply.
Thanks in advance for your help.
Revit 2018.2 and Vray 3.60.02, Boxx pcs with lots of power and gpu, so the pc is not the issue (I hope because I just bought two of them recently).

Update: In the Renderer tab in settings, if I click on Engine - CPU, the fog is maintained in the final render scene. If I click on Engine - GPU, or Hybrid version, then the fog does not render in the scene. I am stuck here, but I hope this added info helps explain my problem or Vrays problem. Thanks again. DpH

Hi Dave,

The Environment Fog is not supported in GPU. From what you have described, I think that that's the case.

Best,
