This a time-lapse of a system I have been working on in order to allow me to layout levels more quickly. I need to get buildings to a workable state quickly so that I can work on game-play, environment as story elements. This system is based on creating rough floor plans lo allow me to quickly generate the geometry based off image maps. The system is hardly revolutionary but it does allow you to get scene elements of the correct scale (especially buildings) very quickly.
