    VrayEnvironmentFog not working with the RTX engine

    Hi,
    I've got a scene that I need to use VrayEnvironmentFog with. The fog renders fine with CUDA, but not with RTX. Please see attached the simplified 3ds Max scene and some screenshots.

    Hey Alex_M​, I've managed to reproduce it and I've added it to our bug-tracking system as VGPU-6221. This is caused by the plane objects that are inside the Box gizmo, which is not working as expected with RTX. If you move them outside, RTX should match CUDA.
