Right had so much fun with this one, I found about this three days ago and just worked as fast as I could on this.
Challenge was the free photogrammetry asset that I used, had to break it down in several chunks for Lumen to work properly. I did not use Nanite simply because of other free assets I planned to use.
Story wise I wanted to get that night + fog / blue + orange setup and show a mystery treasure box in abandon location.
I also used physically correct camera and light values and set light units to Lumen.
Last minute edit, I noticed a light leak on top left of ceiling and quickly fixed it. Issue can be seen in second picture.
