Environment concept design made in Unreal 4. Here I tried to design and visualize a non-typical hideout space for a smaller group of people that, by accident, found an old tunnel that was ending in a vast cave. Tunnels are periodically drained so the boats are stranded for a while. The makeshift wooden dock is used to unload the boats and transport supplies into the hideout.
The cave is a big water reservoir and has many pillar-like rock structures that are used for shelter and housing. Small holes in the ground above the cave create light shafts that "paint" the cave with a unique atmosphere.
