Is the Footbridge 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), 489 KB: 6,704 triangles, 20,112 vertices and 20 materials, modelled in metres at 16 m × 7.0 m × 12 m.

Can I animate Footbridge?

It ships as a static mesh. Its 7 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 Footbridge 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.

Footbridge

A low-poly Victorian station footbridge: two iron-green lattice girders carry a boarded deck between landing towers on cast-iron columns. A staircase with a half landing drops from each tower to platform level, with lanterns on the corners and a lamp standard at each stair foot.

How it was made

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

Footbridge for the Railway 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. It is a modular piece that snaps on a 1 m grid: give it a length in whole metres and put the origin at its snapping end, stated in meta.notes. This is one part of the Railway Station kit (Low-poly style, flat-lowpoly direction): Platforms, signals and a grand hall. Use ONLY the kit palette, by name: brick #9e3d2e, iron green #3a883a, cream #f1e7d0, signal red #e90c0c, brick dark #63261d, iron green dark #235223, brick light #c66253, iron 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 `era` (0–1, default 0.5) for the kit's "Era" setting wherever it makes sense on this part, and keep that id.

Note: Size at the default params: 16 m long (X) × 11.63 m deep (Z, mostly the two staircases) × 6.99 m tall to the lantern tips, with the deck walking surface 4.6 m above platform level and 1.3 m lattice parapets. Modular, snapping on a 1 m grid: the length is whole metres (12–24), the span runs along +X from the origin at its snapping end (x = 0) to x = length, and nothing passes either end plane. The origin is at that end on y = 0 (the platform surface both stairs land on), with the footprint centred in Z; the stairs drop toward +Z (front). No platforms, track or ground are included. The exported model has 6,704 triangles in 20 meshes and is static, with no animation clip. Every material is named exactly after a kit palette colour; 11 of the 12 are used (brick dark is not). The exporter writes one material per mesh, so recolour by name. Params are baked into the GLB at their defaults and only change the model when the scene is rebuilt in the viewer. era (the kit's 'Era') sets the girder lattice: a dense triple criss-cross at 0 (Victorian), a double criss-cross at the default, and a plain Warren truss above 0.67; it also shortens the red lantern finials. deckHeight sets the riser count (about 0.16 m risers, 0.28 m goings, a 1.4 m half landing), so higher decks make longer stairs. width sets the deck, stair and tower width. Both extremes (era 0 / length 12 / deckHeight 5.4 / width 2.6, and era 1 / length 24 / deckHeight 4.2 / width 1.6) were rendered and passed three-check and glb-lint with 0 errors. glb-lint: 0 errors and 6 heuristic warnings: per-mesh duplicate materials, non-indexed geometry (deliberate flat shading), intended nesting overlaps, plinth caps flagged as 'detached' though they sit on the plinths, and the 6.99 m height against a generic 1 m reference. The verdict reads UNVERIFIED only because no host requirements contract was supplied. plan-check passes except for its part-id regex, which rejects the hyphens in the slug-based ids this library requires. With the ids substituted it passes. three-check accepts the real ids, and all 7 survive the GLB reload.
