I'm hoping this is just something that I'm doing wrong, but I am unable to get certain directional lights working properly with volumetric lighting / volumetric fog. I have a scene that is set underground and lit from underneath, so my key light is a directional light facing roughly upwards. I have a standard "Scene Settings" volume object in my scene. When I use linear or exponential fog in my Visual Environment override (along with adding the necessary override) I get expected results. However, when I switch to Volumetric fog, any of my directional lights that are facing upwards at all cease to render at all, including on any surfaces. I only have one directional light facing upwards, but can replicate the behavior with others by pointing them upwards, and aiming the key light at all downwards causes it to start rendering. The behavior does not change based on what settings I have set on the light, including shadows or the volumetric tick box. Even if I could get by with having they key light above the player, I still need to be able to have a light source of some sort below. If there's a solution that involves baking out non-shadow rim or fill lights I could give it a go, but I was unable to get such a solution to work on my own: no matter what process I try, I cannot get any directional lights to register in any way whatsoever if they are angled upwards above horizontal and the scene settings visual environment override has volumetric fog selected. Oh! also - the behavior occurs whether or not I have actually added a volumetric fog override, which I obviously would for the final scenario, but which suggests to me that the issue doesn't have to do with the volumetric fog override itself, specifically. Thanks for any help!
