This is a subway scene which I created during my third year at Digital Arts and Entertainment. For the purpose of this scene I made a few different tools within the engine to see what was possible.
First I made a Spline Tool which I used to create all the wires and pipes in the level. Next up I made a tool which allows for easy tiling of wall and floor pieces with small forms of randomization.
Next up I made a Clutter Volume which allowed me to just fill the level with newspapers and broken tiles in completely random places.
