I like messing around with procedural generation especially using modular elements. I started developing a tool to create large sprawling buildings / castles, that have a maze-like dungeon-crawler feel to them, and starting using bit-strings to match tiles up. I really like the potential of this tool, and wanted to post a basic ‘How-To’ here.
It’s all done in one Blueprint, and I think is has the potential to create some quite interesting results: not just terrain, but buildings (as originally intended) and deco. Hope you find it useful / interesting:
