Creating these buildings was a four day marathon, but it was a big learning experience about developing fast processes for creating future game assets in Blender. The six buildings in this scene are all made from only 10 blocks using 3 texture files, and the application of a lot of Array, Boolean, and Mirror modifiers. With these blocks, I can now create buildings of any floor space dimensions with one to three stories, and place these windows, doors, gates, and internal staircases with a few clicks through drag and drop. These techniques will become invaluable when it later comes to creating whole palaces or underground bases as levels.
