Concrete sidewalks on both sides of the roads with realistic tiling. No buildings, no trees, no vehicles, no props, empty environment. Only detailed road system with intersections and curves. Surrounded by simple flat ground. Seamless asphalt texture, realistic pavement texture. Game-ready, optimized low-poly to mid-poly mesh for mobile. Clean topology, no extra objects.
