I´m doing some test in Unreal 4 with some 3d models that I´ve creating. I love Doom game and I wanted to create a basic level Design inspire in that game.
In the video. I´d use the next asset from Unreal Marketplace: https://www.unrealengine.com/marketplace?sessionInvalidated=true
SciFi "Populate" pack
Mothership Service rooms
the concept art that I used to become in 3d asset is from: Kris Thaler https://www.artstation.com/kristhaler
