Another lighting and level building experiment in Unreal. It was built with the Modular Tech asset pack (https://www.unrealengine.com/marketplace/modular-tech-environment) plus a couple mountain ranges and volumetric particles.
Simple mats view
Just the lighting
Daytime variation
I just liked the view
The volumetric fog is a bit too noisy and defined here.
A cinematic camera run through of the night and day versions
