Is the Bumper cars 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), 129 KB: 1,484 triangles, 2,560 vertices and 22 materials, modelled in metres at 1.3 m × 2.6 m × 2.0 m.

Is Bumper cars animated?

Yes — the GLB carries a baked animation (6.0 s), ready to play with any glTF animation mixer.

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 Bumper cars 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.

Bumper cars

A low-poly fairground bumper car with a thick black rubber bumper ring, open cockpit, steering wheel and a tall trolley pole. It ships with a 6-second seamless loop: the pole sways on its swivel, the collector head turns, the steering wheel swings and the pennant flutters.

How it was made

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

Bumper cars 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 moves: author a seamless baked loop (2–12 s) with every pivot exactly at its hinge, axle or swivel, and keep the base still. 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: 1.32 m wide x 2.02 m long (outside the rubber bumper ring); the car body is 1.04 m tall at the rear cowl, and the trolley pole tops out at 2.59 m. Front faces +Z, the origin is at the bottom centre, and the casters rest on y = 0. 1,484 triangles, flat-shaded with baked flat normals. Materials are named by kit palette colour (candy red, yellow, sky blue, white, soot black, mid grey, warm white, candy red light). The exporter writes one material slot per mesh, so the GLB has 22 slots that share those 8 names; recolour by name. The clip 'scene-motion' (6 s, seamless) moves only four pivots: the pole about its swivel mount on the rear cowl, the collector head about its swivel at the pole tip, the steering wheel about its column axis, and the pennant about its hinge on the pole. The chassis, body and bumper never move. 'Ride colours' picks the body/accent/seat pairing from the palette: below 0.33 sky blue with yellow and a candy red seat, up to 0.66 candy red with yellow and a sky blue seat (default), above that yellow with candy red and a sky blue seat. Params are baked at export, so the GLB holds the default build; Pole sway and Steering swing only change the motion amplitude. Part ids use 'amusementpark.bumper_cars.*' rather than 'amusement-park-bumper-cars.*' because the kit's part-id format does not allow hyphens. glb-lint reports 0 errors; the remaining warnings are expected: the per-mesh material slots, the real-scale height, and trim pieces seated into their parent panels.
