Is the Railings 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), 57 KB: 724 triangles, 1,848 vertices and 9 materials, modelled in metres at 2.1 m × 1.4 m × 30 cm.

Can I animate Railings?

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 Railings 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.

Railings

A low-poly run of Victorian cast-iron area railings: black square bars with brass spearhead tips between a top and bottom rail, square end standards with brass ball finials, on a red-brick dwarf wall with a stone coping. It is a 2 m modular piece that snaps end to end on a 1 m grid.

How it was made

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

Railings for the Victorian Street 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 Victorian Street kit (Low-poly style, flat-lowpoly direction): Gaslight, soot and shop windows. Use ONLY the kit palette, by name: brick red #c32222, soot black #151619, bottle green #3a883a, brass #b28c34, brick red dark #821717, soot black dark #090a0b, brick red light #db5757, soot black light #3a3c40, 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 `fogLevel` (0–1, default 0.5) for the kit's "Fog level" setting wherever it makes sense on this part, and keep that id.

Spearheads and finials

Note: Size at the defaults: 2.0 m between standard centres (2.06 m overall, because the coping overhangs each end by 3 cm), 1.39 m tall to the top of the ball finials, and 0.30 m deep across the coping. The spear tips are at 1.2 m. The brick dwarf wall is 0.36 m tall and 0.23 m thick, under an 8 cm stone coping. The 15 bars are 2 cm square at a 0.121 m pitch. Snapping: the run lies along +X and the origin is its snapping end, the centre of the first standard at ground level (y = 0). The front faces +Z, and the far standard centre sits exactly at x = length, which is where the next piece's origin goes. Both end standards are modelled so a single piece looks finished. When pieces are chained, the shared standard is identical geometry in the same place, and the 3 cm coping overhangs overlap in the same plane, in the same colour. This breaks the library's usual bottom-centre origin on purpose, because the brief asks for an end origin on modular pieces. Standards are at most 2 m apart, so 3 m and 4 m runs get a middle standard. The GLB has 724 triangles in 9 meshes, merged per part and colour, with flat normals, and it has no animation clip. The largest settings (4 m, 1.6 m tall, 0.09 m spacing) stay well under the 6,000-triangle budget. Every material is named exactly after a kit palette colour, and 6 of the 11 colours are used. The exporter writes one material per mesh, so 'soot black' and 'soot black light' each appear more than once: recolour by name. All materials have metalness 0, as the direction requires, so the brass is a flat colour, not shiny metal. fogLevel (the kit's 'Fog level') is the soot the fog leaves on the street: the soot band at the foot of the wall rises from 3 cm at 0 to 10 cm at the default and 17 cm at 1. The fog itself belongs to the street scene. Params are baked into the GLB at their defaults and only change geometry when the scene is rebuilt in the viewer. Only the defaults were rendered and checked. The grey disc in the preview is viewer staging and is not in the GLB. glb-lint reports 0 errors and 3 heuristic warnings: duplicate same-named materials; standard and lead-cap overlap, and the brick and brick-course overlap, both of which are intended nesting; and 'detached' coping, rails, bars and finials, which in fact sit on or pass through one another. plan-check rejects only the hyphenated library part ids, because its regex allows no hyphen. The same plan with the slug de-hyphenated passes, and three-check accepts the ids and all 7 survive the GLB reload.
