Working on a district generator for my cyberpunk game. It has a long way to go, but I am pretty pleased with it so far.
It uses a building system similar to Ark/Conan Exiles/Valheim. Walls/floors/ceilings are basically on a 4m grid.
All buildings have interiors with stairwells that can be explored. They're empty currently.
There's a variety of ways to add new (wall materials / doors / windows / garbage on the street / etc) by dropping (textures / prefabs / models) into specific folders within the project. I would like to add mod support for loading external content via XML, similar to how "7 Days to Die" works.
An upcoming step is to add "rooms" as collections of objects/npc's that can fill up the buildings.
I definitely need some more work on the exteriors though, beyond just adding more door and window options. Like, curbs and some kind of adornment on some of the building corners or something? I could really use some more ideas here if anyone has some thoughts.
