Is the Bones 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), 240 KB: 3,198 triangles, 9,594 vertices and 16 materials, modelled in metres at 2.4 m × 46 cm × 1.6 m.

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 Bones 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.

Bones

The low-poly bleached remains of a Cape buffalo lying in savanna grass: a skull with dark eye sockets and broad hooked horns, a run of vertebrae, a ribcage arching up out of the grass and two scattered leg bones.

How it was made

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

Bones 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. 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: the remains of a Cape buffalo, about 2.45 × 0.46 × 1.57 m (W × H × D) including the grass tufts. The skull is about 0.55 m long with a 0.9 m horn span, and the tallest rib arch stands 0.46 m. The spine runs along X with the back toward −Z. The skull lies palate-down with its muzzle facing +Z. The origin is the bottom centre of the footprint, and the model rests on y = 0. The GLB has 3198 triangles in 16 meshes (merged per part and colour) and no animation clip. Normals are baked flat (non-indexed). Every material is named exactly after its kit palette colour, and 9 of the 12 kit colours are used (earth red, dusk purple and mid grey are not). The exporter writes one material per mesh, so a colour name can repeat: recolour by name. Params are baked at their defaults and only change geometry when the scene is rebuilt in the viewer. dryOrWetSeason (the kit's 'Dry or wet season') changes only the grass. At 0 there are 9 short straw-gold tufts. As it rises toward 1, the grass grows taller, gains up to 5 more tufts and turns mostly acacia green. The bones never change colour. ribCount and ribArch reshape the ribcage, and a seeded few ribs are broken short. hornSpan sets the horn reach. The eye sockets and nasal opening are thin soot-black plates set a few millimetres proud of the skull, not holes. The dusty gold ground disc and the lowered exposure in the viewer are staging only and are not in the GLB. glb-lint: 0 errors. Its heuristic warnings are expected: per-mesh duplicate materials, more materials than the direction default, unindexed flat-shaded geometry, deliberate overlaps (grass through bones, knuckles on shafts), a 'detached' flag on the socket plates (they sit on the skull, which is a different part), and a scale hint (the asset is low by nature). plan-check passes except for 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 8 survive the GLB reload. Fix rounds: (1) a dusty earth stage disc so the pale bones read, a lower, domed horn boss, a removed floating hip plate, and denser grass; (2) a tighter hero frame, and the whole ribs bent down so their tips rest in the grass.
