Environmnet Fog not working in IPR

[LucasMolina]

Hi,
The V-Ray Envrionment Fog is not working in IPR (GPU), if I make a change in the attributes, it desappears completly, then I have to stop the render and run the IPR again to see the update. However the Fog works in CPU mode and I can have the proper interaction.
I'm using Maya 2020.1 and V-Ray 4.30.02
Is there anything I can do?

Cheers,
Lucas

Thanks for the report, it seems to be a recently introduced issue. I've logged it (internal bug-tracker id: VGPU-4833) for developer analysis. Not sure if there is anything you can do except adjust your fog with the CPU IPR or restart IPR after each change in GPU.
