Draw a curve, get a road: lanes, markings, curbs, sidewalks, lamps – and it follows your terrain.

Tidebone Road is a Geometry Nodes generator you drive with a curve and sliders. Pick 1–4 lanes, round the corners of a polyline with Corner Radius, choose a dashed, solid or double centre line, add edge lines, curbs, sidewalks on one or both sides, street lamps at your spacing and manhole covers. Tick Follow Ground, pick your terrain, and the road rides the hills. Two sliders, Asphalt Wear and Paint Wear, take it from freshly paved to cracked, patched and faded.

Features

• Road: 1–4 lanes, lane width 2.4–5 m, rounded corners, resolution slider, outputs Length, Road Width, Lamp Count
• Markings: centre line dashed / solid / double / none, edge lines, lane dividers, dash length and gap, line width, two colour inputs (yellow / white by default)
• Curbs & sidewalks: curb width and height, sidewalk left / right / both, sidewalk width, paving pattern
• Street lamps: side, spacing, height; manholes at a spacing you choose
• Follow Ground: ray cast to any mesh, ground offset, deep slab so no gap shows on slopes
• One look: Asphalt Wear (cracks, patches, stains, faded asphalt) and Paint Wear (chipped, faded markings) drive 4 included procedural materials (asphalt, road paint, paving/curb, metal); attributes tr_color, tr_wear for your own shaders
• Asset-browser ready, demo scene, README with polycount table
• No add-ons, no Python, no image textures. Tested headless on Blender 4.2 LTS, 4.5 LTS and 5.2 LTS: 40 parameter cases each, 0 errors, identical vertex and face counts

What it is not (so you know before you buy): one curve is one road – no junctions, roundabouts, bridges or tunnels, no crosswalks, arrows or signs; the road is not banked across slopes (it rides on the highest terrain point of its width); buildings, trees and cars in the preview images are simple stand-ins and not included.

Included: tidebone_road_kit.blend (generator + 4 materials), asset catalog, demo scene, README, license (Personal 1 seat / Studio up to 10).
