Generate 3D environments easily from real-world data! Buildings, roads, trees, and more are procedurally generated using information from OpenStreetMap. With CityGen3D, you can generate terrain, roads, and buildings based on real-world data from OpenStreetMap. Select your location anywhere in the world and let CityGen3D do all the work without any coding—fully within the Unity Editor. All prefabs and materials shown in screenshots are included in the package, allowing easy recreation of demo environments. The tool is fully customizable, enabling the use of your own materials and models for specific projects and art styles. CityGen3D also serves as an excellent level design tool: modify a real-world map or create your own 2D map from scratch, then generate a 3D scene using rules you define. It can build large, multi-terrain environments with built-in support for terrain streaming, asynchronously loading scenes around the camera at runtime. Prototype new game ideas quickly—create a driving game set in various global locations or an alien invasion scenario in your hometown—accessible through an intuitive interface.
