A blue city made from a handful of basic assets... I made a few variations of building components, each at different levels; base, middle, top and roof. I then setup a plane with four identical particle hair systems, but each scattered a random item of each of the four collections... chucked in a few old spaceships, and a nice little project... I may return one day and add more detail to the basic components, to make a higher detailed city, but this was fine for now!
