Searched but not really a solid answer.
I am using Volumetric Fog in a Exponential height Fog Component.
If I set Viewport Type to Cinematic Viewport and view thru a placed camera, the result is flickering volumetric fog in the distance.
I can disable it by simply unchecking Volumetric Fog in my Exponential Height Fog or viewing thru the Default Viewport.
Is there a command console setting perhaps I can try?
The solution seems to be indirectly related to Ray Tracing as if I disable DX12 it seems to go away.
At least this setting was removed in my DefaultEngine.ini settings
DefaultGraphicsRHI=DefaultGraphicsRHI_DX12
Also the issue is not simply Volumetric Fog by itself bu the interaction of Spotlights and Volumetric Fog.
Hey! I fixed it by increase r.ScreenPercentage to 200 in console variables in Movie Render Queue settings, it’s for rendering of course. For viewport I don’t know how to fix it
The command “r.VolumetricFog.GridSizeZ 1024” can give you thinner rendering of volumetrics. Use with precaution. Crank up to get better looking fog.
