Is the Light aircraft 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), 154 KB: 1,436 triangles, 4,308 vertices and 22 materials, modelled in metres at 11 m × 2.9 m × 8.9 m.

Is Light aircraft 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 Light aircraft 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.

Light aircraft

A low-poly six-seat high-wing bush plane in warm white and earth red, with strut-braced wings, a two-blade propeller and fixed tricycle gear on fat bush tyres. A 6-second loop turns the propeller and swings the rudder, ailerons and elevators on their hinges.

How it was made

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

Light aircraft for the Savanna 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 Savanna kit (Low-poly style, flat-lowpoly direction): Golden grass and big animals. Use ONLY the kit palette, by name: straw gold #d0a225, acacia green #3a883a, earth red #c32222, dusk purple #572e6b, straw gold dark #8f7019, acacia green dark #235223, straw gold light #debd63, acacia 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 `dryOrWetSeason` (0–1, default 0.5) for the kit's "Dry or wet season" setting wherever it makes sense on this part, and keep that id.

Note: Size: a Cessna 206-class bush plane, about 8.75 m long, 11.0 m wingspan (wingSpan param 10–12 m) and 2.9 m to the fin tip; cabin about 1.2 m wide. The nose faces +Z, the origin is at the bottom centre, and the three tyres rest on y = 0 on flat facets. The GLB has 1,436 triangles in 22 meshes (merged per part and colour) and one baked 6 s clip, 'scene-motion', sampled at 30 fps: the propeller turns 6 whole revolutions on its crankshaft axis, the rudder sweeps once, the ailerons deflect opposite each other twice and the elevators nod once, each on a pivot node on its hinge line. Fuselage, wings, gear and wheels never move. The GLB's static node pose is three-check's t = 2 s export frame, so moving parts sit mid-motion when no clip plays. Every material is named exactly after its Savanna palette colour; the exporter writes one material per mesh, so a name repeats across materials — recolour by name. Normals are baked flat (non-indexed). Windows are opaque tinted panels, no interior. Params are baked at their defaults and only change the model when it is rebuilt in the viewer: dryOrWetSeason (the kit's 'Dry or wet season') paints the belly band from pale straw dust (dry) through dried mud to dark-wood mud (wet) and splashes it higher up the sides as it gets wetter; wingSpan stretches the tapered outer wing panels and ailerons; tyreSize swaps bush-tyre radius (gear legs follow); controlSweep changes the baked loop amplitude. glb-lint: 0 errors, heuristic warnings only (per-mesh material count/duplicates, deliberate unindexed flat shading, patches overlapping the fuselage, hinged surfaces and the belly band flagged as 'detached', 2.9× height vs the direction's 1 m reference). plan-check passes except its part-id regex, which rejects the hyphens in the slug-based ids this library requires; the same plan with the slug de-hyphenated passes. three-check accepts those ids and all 14 survive the GLB reload.

About the Light aircraft 3D model
