Simple Little City Generator is a geometry nodes system for creating small, simplified urban environments. Users build the road network by extruding street layout geometry, which automatically generates neighborhoods of instanced assets.

The system includes controls for building spacing, distance from intersections, and instancing probability based on building size. Greenery can be generated automatically along city boundaries or restricted to manually defined areas. Users can also control instance distribution using texture inputs, manage traffic, pedestrian, and street light frequency and speed, and define dedicated zones where instancing is restricted. The setup includes population and tree counters, and a proximity-based animation feature for city growth.
