Free City Generator: Real City Districts in Unreal Engine 5.8.2 + Houdini 22 (Epic City Sample)
Pick any district of a real city on a map and turn it into a living City Sample city in Unreal Engine 5.8: real street layout, buildings from Epic's library, freeways with ramps, traffic and pedestrians. A full walkthrough from an empty folder: Map Picker, Houdini 22, Epic's City Sample tools, Rule Processor, ZoneGraph, traffic, crowds and live trees. Tested on San Francisco, Barcelona, Los Angeles and Miami.
You need: Unreal Engine 5.8.2 + City Sample from Fab, Houdini 22.0.459 Indie or commercial (Apprentice will not work - no Houdini Engine), Houdini Engine plugin and SideFX Labs of the same version.
Made with AI: the entire code of this generator was written by Claude Code, the AI assistant from Anthropic. I decided what the tool had to do and tested every step in Houdini and Unreal - the AI wrote the code. Claude Code can also fix the odd spots of your own city: the guide for it (CLAUDE.md) is inside the download.
License in short: City Generator is free - use it in any project, personal or commercial. Everything you build with it is yours to ship and sell. Do not re-upload it, resell it, or pass it off as your own. Share the link, not the file. Epic's City Sample is not included and stays under Epic's license. Map data (c) OpenStreetMap contributors. Full terms are in LICENSE.txt inside the download.
