Is the Dormitory 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), 393 KB: 5,156 triangles, 15,468 vertices and 38 materials, modelled in metres at 18 m × 11 m × 9.7 m.

Can I animate Dormitory?

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 Dormitory 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.

Dormitory

A low-poly two-storey brick fire-station dormitory with rows of bunk-room sash windows, a gabled roof lined with dormers and end chimneys, and a red canopy over the front door flanked by alarm lamps. A brick pole bay on the end wall shows the crew's brass sliding pole in a tall glazed slot.

How it was made

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

Dormitory for the Fire Station 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 Fire Station kit (Low-poly style, flat-lowpoly direction): Ready for the alarm. Use ONLY the kit palette, by name: engine red #c32222, brick #9e3d2e, brass #b28c34, white #f4f1ec, engine red dark #821717, brick dark #63261d, engine red light #db5757, brick light #c66253, 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 `engineLivery` (0–1, default 0.5) for the kit's "Engine livery" setting wherever it makes sense on this part, and keep that id.

Note: Size: about 17.7 m wide (x, including the 1.8 m pole bay on the right gable and the 0.4 m roof overhangs), 9.7 m deep (z, including the 1.1 m door canopy) and 11.5 m tall to the chimney pots (default params). The block is 14.8 m × 8 m with a 3.3 m ground storey, a 3.0 m bunk storey, eaves at 6.3 m and the ridge at about 9.7 m under a 40° roof. The front door faces +Z, the origin is at the bottom centre of the footprint and the model rests on y = 0. The GLB has 5,156 triangles in 38 meshes (merged per part and colour) and no animation clip. Normals are baked flat (non-indexed), so the facets survive in any engine. Every material is named exactly after its kit palette colour and all 12 kit colours are used at the default livery; the exporter writes one material per mesh, so the same colour name appears on several materials: recolour by name. engineLivery (the kit's 'Engine livery') repaints the front door, canopy and pole-bay slot frame in three bands: below 0.33 a white door, engine red canopy and frame; 0.33–0.67 an engine red door, engine red dark canopy and white frame (default); above 0.67 an engine red dark door, engine red canopy and brass frame. lightsOn sets the share of bunk-room windows glazed in brass (lit) instead of soot black; which rooms light is seeded and fixed. bayCount changes the length (3 bays ≈ 12.5 m wide, 7 bays ≈ 22.9 m). At shallow pitches the dormers shrink and the back dormer roofs can show just over the ridge from low front angles; that is real geometry, not a stray part. The windows are flat glass with no interior. Params are baked into the GLB at their defaults and only change geometry when the scene is rebuilt in the viewer. glb-lint: 0 errors; its heuristic warnings (material count and duplicates from the per-mesh export, unindexed flat-shaded geometry, sibling overlap from trims embedded in walls, scale against the direction's 1 m reference) are expected. plan-check passes except for its part-id regex, which rejects the hyphens this library's slug-based ids need; the same plan with the slug de-hyphenated passes, and three-check finds all 8 ids in the scene and after the GLB reload.
