Is the Cul-de-sac road tiles 3D model free for commercial use?

Yes. It is free under the 1DesignTool 3D library license: use it in personal and commercial work — games, apps, websites, renders, ads and client projects — and modify it as you like, with no credit required. What you can't do is re-sell or re-distribute the file on its own or inside a model pack.

What file format is it, and how big is it?

A single binary glTF 2.0 file (.glb), 120 KB: 1,128 triangles, 3,260 vertices and 16 materials, modelled in metres at 4.0 m × 1.3 m × 4.0 m.

Can I animate Cul-de-sac road tiles?

It ships as a static mesh. Its 8 named parts are separate nodes, so you can move or animate each one in your engine.

Which engines and tools can open it?

Anything that reads glTF 2.0. three.js, React Three Fiber, Babylon.js, Godot 4 and Blender import the GLB directly; Unity and Unreal Engine load it through their glTF importers. The snippets above show the exact code for three.js, React Three Fiber, Godot and Blender.

How was the Cul-de-sac road tiles 3D model made?

Claude Code (Claude Opus 5.5) generated it inside 1DesignTool's 3D template from a written brief, then the design kit's checks verified the geometry and the GLB before it was published. You can make your own the same way with 1DesignTool.

Cul-de-sac road tiles

A low-poly 4 × 4 m street tile where an asphalt lane ends in a faceted turning bulb. A grey curb and pale sidewalk ring the bulb, with lawn corners, a manhole, a storm drain, two mailboxes and shrubs around it. It is the dead-end piece for a suburban road grid.

How it was made

The brief given to 1DesignTool's “3D object” template:

Cul-de-sac road tiles for the Suburban Street kit. Design it as one clear asset at believable real-world scale for that setting (state the size in metres in meta.notes), with its main parts modelled and named, readable at thumbnail size and from every orbit angle. Make it a ground piece on an exact 4 × 4 m footprint with flat edges at y = 0 that tile seamlessly with its neighbours in every direction; origin at the tile centre. This is one part of the Suburban Street kit (Low-poly style, flat-lowpoly direction): Quiet family homes on a curved road. Use ONLY the kit palette, by name: pastel siding #c4c4c4, lawn green #3a883a, asphalt #3b3e45, white trim #f4f1ec, pastel siding dark #9e9e9e, lawn green dark #235223, pastel siding light #ebebeb, lawn green light #5db15d, soot black #1b1b22, warm white #f2ede2, mid grey #7d828c, dark wood #3d2a1c. Every material's `name` must be exactly the palette colour it uses — the GLB carries these names so the kit recolours as one; an unnamed material fails delivery. Kit knob: expose a param `houseColours` (0–1, default 0.5) for the kit's "House colours" setting wherever it makes sense on this part, and keep that id.

Note: Size: exactly 4.00 × 4.00 m footprint and 1.26 m tall at the mailbox flags; the ground surfaces are 0.15 m thick. The origin is at the tile centre, the bottom rests on y = 0 and the front faces +Z. The lane enters through the back (−Z) edge and ends in a 1.35 m radius turning bulb. This is kit scale, not survey scale: a real cul-de-sac bulb is about 18–20 m across, so the street is compressed to fit one 4 m tile, and the 2 m lane matches the kit's miniaturised road. How it tiles: every slab rises straight from y = 0, so all edges are flat walls. The ±X and +Z edges are lawn at 0.15 m. The back edge is the road cross-section, centred on x = 0: a 0.35 m sidewalk and 0.12 m curb on each side, both 0.15 m high, around 2.0 m of asphalt at 0.05 m. It meets any straight road tile with the same section, and the centre dashes repeat on a 1 m rhythm. The GLB has 1,128 triangles in 16 meshes, is static and has no animation clip. Every material is named after its kit palette colour, so you can recolour by name. The exporter writes one material per mesh, so mid grey, pastel siding dark, soot black and white trim appear more than once. Warm white is used only when houseColours selects it. houseColours (the kit's 'House colours') picks the siding swatches of the two mailboxes so they match the houses: warm white, pastel siding light, pastel siding or pastel siding dark, with the second mailbox one step along. At the default they are pastel siding and pastel siding dark, and both read light in the viewer. The GLB is baked at the default params, and only the defaults were rendered and checked. roadWidth, bulbRadius and shrubs rebuild the tile in the viewer only; the bulb is always kept wider than the lane. glb-lint: 0 errors and 5 heuristic warnings, all expected: more than 10 materials and duplicated palette names because of one material per mesh; non-indexed flat-shaded geometry; nested manhole/shrub bounding boxes; and mailbox posts flagged as 'detached' because they are seated 5 cm into the lawn, which lives in another group. plan-check rejects only the hyphenated library part ids (its regex allows no hyphen); three-check and the GLB carry all 8 ids correctly.
