DK Procedural City

DK Procedural City generates a complete, playable Unity city from a single seed. The generation core is fully deterministic — the same seed always produces the same roads, blocks, zoning, plots and buildings — so it's safe to test against and safe to ship in a shipped build.

On top of that core sits a full rendering and runtime layer: catalog-driven building prefabs, live traffic with signals and curved roundabout lanes, a pedestrian crowd that stays on the sidewalk and crosses only on a red light, a day/night cycle with lit windows and street lamps, weather (rain with reflective puddles, snow, fog), and a performance layer (mesh combining, GPU instancing, distance culling) proven on a 500x500, 690-building stress test.

Everything is customizable: drag your own building, vehicle and prop prefabs into the no-code catalog — nothing is hard-wired to the bundled demo models. A toolkit editor window exposes presets, seeds and generation settings without touching code. Works with URP, HDRP and Built-in from a single codebase.

Suitable for city-builders, traffic/driving games, open-world backdrops, architectural visualization, and any project that needs a populated urban environment without hand-placing every building.
