[UE4] Valley lighting atmosphere study

This is my attempt to create a lighting atmosphere for a large scale scene.
Since the scene is very large, I did not use lightmass baking. I use completely real-time lighting. And I didn't use rough LPV.

Many thanks to Alireza Khajehali for the scene levels.

Thanks to Harry "deBug" Emelianov for the volumetric clouds, the effect of the clouds is great!
