Creating a city for a game often means spending a lot of time on repetitive setup before you can start working on gameplay, lighting or level design. Metropolygonia is designed to speed up that early stage. You can generate a street network, automatically divide it into building plots and populate the layout with your own saved procedural buildings.

This makes it possible to quickly create different versions of an urban environment and test:

* street scale and navigation
* building density
* gameplay spaces and sightlines
* different architectural styles
* overall city composition

Buildings can be generated with interiors, real-world dimensions, UVs and PBR materials. You can export the results as GLB, glTF, OBJ or STL and continue working in tools such as:

* Unreal Engine 5
* Unity
* Godot
* Blender
* Maya
* 3ds Max
* other 3D software supporting these formats

The idea is to provide a flexible starting point rather than a finished, locked environment. You can generate the base city in the browser, then adjust the geometry, materials, collisions, lighting and gameplay elements in your preferred engine or DCC software.

I built a browser-based procedural city generator for indie game development - now with automatic street layouts. This is free for non-commercial projects.
