When generating buildings, think modular! All the good game designers do this. They decide on a visual theme for the current level, and then generate a few building components that fit together well and that can be placed throughout the level. These buildings are fillers. You will learn how to create a more detailed building (which can also be explored inside) in Chapter 9, The Main Building — Inside and Out. For now, the name of the game is speed.
For this quick method, you will need to find and download some building frontage textures from somewhere like CGTextures.com. Go for full buildings and some generic images, such as the side or rear of a disused building. Also, grab a couple of windows and shutter doors.
