Chernobyl - A Lighting Study in Unreal Engine

I had a recent chat with one of my good friends and awesome lighting artist Kevin Dalziel about how much we loved the visual treatment of the gut wrenching HBO mini-series, Chernobyl. That sparked some inspiration for a late night lighting study in Unreal Engine , using some of their ray traced functionalities within a fully dynamic lighting pipeline, all while hitting 60 FPS at 4K on my Nvidia RTX 2080 Ti. I used traditional UE4 post processing and tone mapping first. I authored my lighting with physically based values and also altered the default tone mapping settings to produce a linear image as much as possible (My UE4 equivalent of a camera RAW image). And once I got there, I played with the shadows, midtones and highlights within the UE4 post processing settings. And finally topped it off with a custom LUT that I made in PS.
