    First we thought this is only us but this is in V Rising as well
    The fog goes NAN at a random time, which proceeds to clear the fog voxels with black or something like that

    This starts small and then spreads over the screen.






    Players get this a lot.

    Hey,
    It appears that it is just a matter of time
    So if you are in the same scene for a longer duration, it is basically guaranteed, however can also appear quite instantly, so maybe some random noise value is going negative maybe at some point with a very tiny chance or something like that, it appears to be random based

    Turning the Fog on and off does clear it so it must be the fog or the denoising of the fog
    If you wait 15 minutes there should be a high chance of it appearing

    Ill see if we can export something
