A whole city,
generated in seconds.
CityForge is a procedural city generator for Unity URP — with real windows, furnished rooms behind them, balconies, shop fronts and street lights that actually light the street.
Everything below is generated by the tool — no hand placement, no baked scene.
Most city generators stop at the silhouette. CityForge keeps going — so the camera can walk down the street without the illusion falling apart.
Windows are actual openings with real rooms behind them: walls, floors and furniture placed with collision checks. Not a texture trick.
Three calibrated looks with post-processing. At night, lit rooms, neon signs and a real light on every street lamp carry the scene.
Rows, heights, tower and shop ratios, balconies, interior density, parks, street props — tweak and regenerate from a single dockable panel.
The same seed rebuilds the exact same city on any machine. Commit a tiny profile asset instead of a 100 MB scene.
Shorter shadow distance, fewer probes and optional colliders on buildings, ground and sidewalks — ready for characters and raycasts.
Original code and shaders plus CC0 (public-domain) assets, fully documented.
Everything lives in one folder: Assets/CityForge.
All shots come straight from the generator — only the camera was placed by hand.
Same tool, different profile settings — no extra asset packs.

I'm an indie developer working on my own game in Unity. I needed a city for it — a real one, not a grid of grey boxes — and the assets I could afford fell apart when the camera got close. So I started writing my own generator.
It grew slowly: punched windows instead of painted ones, then real furnished rooms behind those windows, balconies, shop fronts, street lights that actually light the street. At some point it stopped being a shortcut for my game and became something worth sharing, so I cleaned it up and released it as CityForge.
Everything I publish is something I use myself. I'm one person, so I can't promise huge catalogues or instant updates — but I can promise honest descriptions, no hidden limitations, and an answer if you write to me.
Questions, bug reports, feature requests — all welcome. If the generator can't do something you need, tell me; that's how it got this far.
