Brown city

Brown City is a detailed modular urban environment.

Build your own streets using the organized prefab library, or start with the included Block 01 demo scene containing 1,241 editable prefab instances. The pack includes buildings, roads, sidewalks, street furniture, signs, traffic-control objects, vegetation, decals, pipes, ducts, and environmental effects.

Brown City also includes custom Scene View tools that make environment customization fast and intuitive. Paint graffiti and damage decals directly onto surfaces, draw editable pipes and rectangular ducts, recolor brick buildings per instance, and preview complete day or night lighting without entering Play Mode.

Animated details help bring the environment to life: traffic lights cycle automatically, cinema lettering flickers, steam rises from drain grates, street lamps illuminate the scene at night, and small insect swarms appear around selected lights.

Interactive props include open and closed manholes, adjustable trash-can lids, single and double chain-link gates, and controllable steam vents. These states can be configured in the Inspector and gates animate during Play Mode.

All release geometry is supplied as native FBX with standalone URP materials.
