A new, work in progress mod that adds L-system cities to No Man's Sky. The L-system is a custom one created as a stand alone general purpose application,by me , that generates cities . It was then tweaked to work with No Man's Sky.The city Layout is decided by the L-system It also incorporates procedural generation when deciding what parts to use. Some features of the city generator:

1) it can accept any number of modular parts as input for city generation.
2) it can create cities of any size . increasing the complexity of generation increased the city size. a increase in complexity by one, doubles the size of the generated cities.
3) highly customizable and modular organisation of city generator,
4)multiple levels/floors possible, though not shown yet.
5) a unique, custom created overlap prevention feature that prevents parts from overlapping over one another.
6) special termination prediction and optimization system that prevents dead ends from spawning and joins nearby building parts together.
7) it even has procedural interiors, procedural roofs etc all reused from the game parts.
8) It can even generate cities to cover entire planets.

This video showcases two random cities(complexity level 2) from the Mod, and then showcases the parts used, the comparison of complexity levels of city sizes. it is textured to have a blade runner type vibe at night time.


it currently does not have NPC's yet , it still needs to be added.adding NPC's to populate the cities will add a level of activity never seen before. The parts dont have collisions yet due to a problem in nmsdk and some more features like animated doors etc are still not implemented yet since its in a very early stage.
