Exaro Road & Street Builder

Draw a road and Exaro Road & Street Builder builds the street along it: lanes, curbs, gutters, sidewalks, parking, medians, shoulders and verges, painted to real marking rules and graded into your landscape. Draw another road across it and the junction builds itself: curb returns, crosswalks, curb ramps with tactile strips, stop bars, turn arrows, STOP and YIELD signs, street names, or a signalised junction with mast-arm signals that cycle in game.

**15 road types**: US Suburban, US Downtown, Rural Two-Lane, Divided Boulevard, Highway, Urban Freeway, Ramp, Industrial, Cobblestone Street, Brick Street, Gravel Road, Dirt Track, Alley, and two roundabout rings. Swap a road's type at any time and the same spline rebuilds.

**Junctions and roundabouts** - T and cross junctions at any angle, with stop, yield, uncontrolled or signal control. - Signal timing per junction; the lights cycle in play and keep cycling after you bake. - One- and two-lane roundabouts: entries yield, splitter islands, planted island. - Drop a road's end on another's to join them: same type becomes one road, different types blend over 15 m.

**Bridges and tunnels** - Bridges with deck, barriers, piers and abutments; approach guardrail bolted to the parapet. - Tunnels in horseshoe, box or round section, with headwall, stone or brick masonry, or hood portals, ceiling lights and lane signals. The landscape opens at each mouth.

**A street that dresses itself** - Street lights (lighting opt-in, no hidden cost), speed limit signs in mph that match the road, curve warnings, benches, bins, meters, hydrants, street trees, utility poles with wires. - W-beam guardrail on bends and bridge approaches, concrete barriers and noise walls on freeways. - Condition from new to abandoned: sealed then open cracks, repair patches, potholes, worn and chipped paint, weeds, litter, bent signs, tipped bins, broken lamps. Wetness and marking wear sliders.

**Ship what you build** - Bake the whole network to merged static meshes and instances, or keep it live. - ZoneGraph lanes for Mass traffic and crowds; a lane graph for your own AI. - Semantic road data (lanes, edges, zones, junctions) for Blueprint, Python and PCG. - Every mesh, material and rule is editable data. Bring your own meshes.

**Included kit (Nanite with LODs, simple collision, true US sizes)**: 60 MUTCD-style sign assemblies, cobra-head and acorn lights, mast-arm signal, W-beam guardrail, jersey barriers with anchors and glare screen, noise wall, utility pole, bench, litter bin, parking meter, hydrant, bollards, cone, Type III barricade, street maple and shrub, worn variants.

Includes a demo map with every road type, junction control, a roundabout and the condition levels.
