Thanks @Remy_Unity , that was exactly what I was missing. I didn’t see anywhere that was necessary and no one else was talking about it so I must have just missed over that.
@Monsterwald Things have moved a bit since my screenshot, but the setting I mentioned is the 3rd toggle form your screenshot.
There is no more “high resolution volumetrics” as it can be controlled directly on the volume override component.
If you are still not seeing volumetric fog, check that it is enabled on the camera frame settings.
