Is the Balloons 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), 89 KB: 1,236 triangles, 2,562 vertices and 6 materials, modelled in metres at 1.0 m × 2.1 m × 94 cm.

Can I animate Balloons?

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 Balloons 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.

Balloons

A low-poly bunch of seven faceted party balloons in candy red, sky blue, yellow and white, crowned by a foil star. Their ribbons fan down to one knot and a single ribbon runs to a small weight on the ground.

How it was made

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

Balloons 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. 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: the bunch is 2.07 m tall, 0.94 m wide (X) and 0.86 m deep (Z). Each latex balloon is 0.28 m across and 0.355 m tall; they float with their ties about 1.35 m up. The foil star is 0.44 m across and faces +Z. The weight is a 0.14 m hex block, 0.09 m tall. The origin is at the centre of the weight's base, and the model rests on y = 0 with +Y up. The GLB is baked at the default params: 1236 triangles, 20 meshes and 6 materials. Each material is named exactly after its kit palette colour (candy red, sky blue, white, yellow, mid grey, soot black), so the kit can recolour by name. The geometry has flat facet normals baked in (indexed, with only identical vertices welded), so it shows faceted in any engine without a flat-shading flag. It is static, with no animation clip. Each balloon part holds its body, neck tie and its own ribbon down to the gathering knot. The ribbons are taut and point straight along each balloon's axis, the way helium pulls them. Ride colours (the kit knob): 0 gives the dark red and yellow shades, 0.5 (the default) the base colours, and 1 the light shades. Values in between mix the tiers balloon by balloon, set by a fixed seed. Blue and white do not change. Balloon count, ribbon length and spread only rebuild the model in the viewer. A relaxation pass keeps balloons from touching at every value; both extremes were built and passed three-check. glb-lint: 0 errors. Its one warning is heur/scale, because it compares the 2.07 m height with the direction's generic 1 m reference height; 2.07 m is the intended real-world size. The verdict reads UNVERIFIED only because no requirements contract was supplied. plan-check rejects only the hyphenated library part ids, because its regex allows no hyphen. A de-hyphenated copy of the plan passes, and three-check and the GLB carry all 12 ids. The project's runtime export was changed to reuse one material copy per source material, so shared materials are no longer duplicated per mesh in the GLB.

About the Balloons 3D model
