Diamond Mine - Realtime environment

This place is an abandoned small urban complex near to a former diamond mine. I wanted to recreate this place described in a book by Fulvio Romanin not yet published.
The environment is made in Unreal Engine 4 and you can explore it in realtime. Assets from Brushify.io, Quixel Megascans and SketchFab (car and buildings by Greg McKechnie, Yury Misiuk and Mikhail Volkov).
