Which component should be improved?

Rendering

Describe your feature suggestion in more detail

After the volumetric finally come to strata it's would be cool if implemented

It's would be usefull for : -Improves lighting immersion, especially in foggy or dusty environments. -Create a sort-off "godays". -Improved visual quality for outdoor and atmospheric scenes

how it's can work : volumetric lighting would be derived from the direction of env_cascade_light/light_environnement(since you can choose if you prefer csm entity or light_environnement direction) .
