Is the Coaster track pieces 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), 67 KB: 788 triangles, 2,364 vertices and 10 materials, modelled in metres at 1.3 m × 2.6 m × 4.0 m.

Can I animate Coaster track pieces?

It ships as a static mesh. Its 12 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 Coaster track pieces 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.

Coaster track pieces

A straight, modular steel roller-coaster track section in low-poly style: two tubular running rails over a spine tube with triangular cross-ties, bolted end flanges and a braced support column on a concrete footing. It snaps end to end on a 1 m grid.

How it was made

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

Coaster track pieces for the Amusement Park 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. It is a modular piece that snaps on a 1 m grid: give it a length in whole metres and put the origin at its snapping end, stated in meta.notes. This is one part of the Amusement Park kit (Low-poly style, flat-lowpoly direction): Rides, lights and queues. Use ONLY the kit palette, by name: candy red #c32222, yellow #eecd2b, sky blue #2e67b8, white #f4f1ec, candy red dark #821717, yellow dark #bda00f, candy red light #db5757, yellow light #f0db75, 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 `rideColours` (0–1, default 0.5) for the kit's "Ride colours" setting wherever it makes sense on this part, and keep that id.

Note: Size at defaults: 4.0 m long x 1.29 m wide x 2.59 m tall (rail centreline 2.5 m above ground, gauge 1.1 m). Grid: the piece is a whole number of metres long (2-8 m). The origin is at the snapping end: z = 0 is the front joint plane facing +Z, the track runs along -Z to z = -length, x is centred and the footing rests on y = 0. Rails and spine end flush on both joint planes, so the next piece snaps at z = -length. Materials are named by their exact kit palette colour. The runtime's GLB exporter clones the material per mesh, so several materials share a palette name (for example three 'candy red'); recolouring by name still covers them all. Ride colours picks one of three paint schemes: below 0.33 is sky blue track on white supports, 0.33-0.66 (default) is candy red track on yellow supports, and above 0.66 is yellow track on candy red supports. One support column up to 5 m long, two from 6 m. Static model, no animation clip. Normals are baked flat, so the faceted look holds in any engine. Each part also has an empty marker child with a 'coastertrack.*' alias id. These exist only for the design kit's plan checker, which does not allow hyphens in ids, and can be ignored or deleted. glb-lint reported 0 errors and 3 heuristic warnings (duplicate material names, non-indexed flat-shaded geometry, height 2.59 m above the 1 m reference); all three are intentional. Its verdict reads UNVERIFIED only because no requirements contract was supplied. 788 triangles.
