Is the Concourse 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), 232 KB: 2,748 triangles, 8,244 vertices and 49 materials, modelled in metres at 12 m × 4.4 m × 8.1 m.

Can I animate Concourse?

It ships as a static mesh. Its 10 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 Concourse 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.

Concourse

A low-poly cutaway of an underground subway ticket hall. A row of steel fare gates with safety-yellow paddles stands under a sign gantry and splits the white-tiled hall into an unpaid and a paid side. It also has ticket machines, a ticket office, a paid-area railing and a railed stairwell leading down to the platforms.

How it was made

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

Concourse for the Subway 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 Subway Station kit (Low-poly style, flat-lowpoly direction): A busy underground stop. Use ONLY the kit palette, by name: tile white #f4f1ec, safety yellow #ffdd33, steel #7e8c9a, line colour #988e81, tile white dark #d7cebc, safety yellow dark #e6bf00, tile white light #f9f8f6, safety yellow light #ffea80, 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 `lineColour` (0–1, default 0.5) for the kit's "Line colour" setting wherever it makes sense on this part, and keep that id.

Note: Size: the hall is 12 m wide × 8 m deep. The floor slab is 0.75 m deep and the walls rise 3.6 m above the floor, which puts the wall caps at 4.43 m. It is a cutaway with walls on the back (−Z) and left (−X) only and no ceiling, so the space reads from above. The open entrance side faces +Z. The origin is at the bottom centre and the slab rests on y = 0. The stairwell drops five steps to y = 0 and then into a dark pit: the flight continues out of sight toward the platforms, which are separate kit parts. The GLB has 2,748 triangles across 49 meshes (merged per part and colour) and no animation clip. Normals are baked flat (non-indexed), so the facets survive in any engine. All 12 kit colours are used, and every material is named exactly after its palette colour. The exporter writes one material per mesh, so the same colour name appears on several materials: recolour by name. Params are baked into the GLB at their defaults and only change the geometry when the scene is rebuilt in the viewer. lineColour (the kit's 'Line colour') sets how much line-colour livery the hall carries: the wall frieze (0.15–0.60 m tall), the share of the gantry sign given to the line-colour panel (25–75 %) and the booth fascia. hallWidth and hallDepth resize the hall, and the stairwell, gate line and machines follow. gateLanes sets the number of fare-gate lanes (3–6), and the last lane is always the wide accessible one. glb-lint: 0 errors and 6 heuristic warnings. Two cover the material count, both from the per-mesh materials. One flags non-indexed geometry, which is deliberate flat shading. One flags overlaps where trim, grout and panels are deliberately embedded. One flags the railing as 'detached' because it stands on the floor slab, which belongs to another part group. The last compares the height with the direction's 1 m reference. plan-check passes except for its part-id regex, which rejects the hyphens in the slug-based ids this library requires. three-check accepts those ids, and all 10 survive the GLB reload. Under the direction's bright sun rig, the yellow guide path reads paler from above than on vertical faces.
