I recently posted a sci-fir door (https://www.artstation.com/artwork/2nBYJ) I'm currently working on for an environment. I wanted to share some of the other models and tiles that I plan on putting in the environment. I'm going to put the sci-fi apartment in marmoset and use the modular tiles to create a hallway in Unreal 4. These are still a work in progress so please share your opinion at any time.
