I decided to go back to the drawing board and overhaul the architecture, models, and textures of the abandoned school for the urban exploration mission in Site 37. I believe it was for the better and I was able to bring out more detail and atmosphere in the level. The old architecture looked a bit too spacious and "fancy" for an abandoned school, in my opinion.

Some areas seen in the screenshots below are a bit brighter than the intended end product. This is mostly for showing off the area in screenshots though the area is still very much a work in progress and lighting is one of the areas that I am looking to improve upon in Unreal Engine 4.
