TimeSplitters Rewind UE4 - Compound Lighting

I have been working with the Timesplitters rewind team as a Lighting artist. Here are some of my WIP's so far for the Compound map.

The map uses Dynamic, emissive and pre baked lighting. I tried reducing the amount of volumetric fog on this map by only using static volumetric fog. This map also uses a custom sky sphere that I painted in photoshop using several HDRI images, which I graded to night. I played around with the environment diffuse to create more light and colour bounce. I am also using dynamic mesh fields multiplied with screen space AO. I tried to focus on creating clear warm and cold sections for the exterior. The interior is still in progress so will post update soon.
