Is the Billboards 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), 67 KB: 690 triangles, 2,070 vertices and 22 materials, modelled in metres at 6.3 m × 6.8 m × 2.6 m.

Can I animate Billboards?

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 Billboards 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.

Billboards

A low-poly roadside billboard: a back-to-back poster head in a grey frame on a single tapered steel pole, with a catwalk, guard rail, ladder and floodlights. The traffic side shows an open road running to an orange sun; the back shows black roadworks chevrons on orange.

Left rail: colours and the 3 knobs the agent wrote into this model — they rebuild the geometry and go into your download. Right rail: looks for the viewer. Drag to orbit, scroll to zoom.

How it was made

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

Billboards for the Highway and Roadworks 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 Highway and Roadworks kit (Low-poly style, flat-lowpoly direction): Lanes, junctions and cones. Use ONLY the kit palette, by name: asphalt #3b3e45, line white #f4f1ec, cone orange #ed7e1d, sign green #3a883a, asphalt dark #17191c, line white dark #d7cebc, asphalt light #636569, line white light #f9f8f6, 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 `countryRoadRules` (0–1, default 0.5) for the kit's "Country road rules" setting wherever it makes sense on this part, and keep that id.

Note: Size: 6.32 m wide (X), 6.76 m tall and 2.58 m deep (Z), including the floodlights that lean out in front. The poster is 6.0 × 2.6 m with its bottom 4.0 m above the ground, on a 0.64 m tapered 12-sided steel monopole. The origin is at the bottom centre of the footprint and the model rests on y = 0, with the traffic side toward +Z. The GLB is baked at the default params: 690 triangles in 22 meshes. It is static, with no animation clip. Every material is named after its kit palette colour, so you can recolour by name. The exporter writes one material per mesh, so palette names repeat. Both posters are flat modelled shapes, with no text or logos. Country road rules (the kit's knob): at 0 you get a 7.2 × 3.0 m motorway face. Towards 1 the face shrinks to 4.8 × 2.2 m and drops by up to 1 m. Above 0.6 the steel monopole and ladder become twin timber posts with white reflector bands, which adds the 'dark wood' material. clearance and lampCount rebuild the model in the viewer only. Both extremes passed three-check: motorway with 6.5 m clearance and 5 lamps, and country with 3 m clearance and no lamps. glb-lint: 0 errors and 6 expected heuristic warnings: material count and duplicate palette names (one material per mesh), non-indexed flat-shaded geometry, nested overlaps (poster layers on the panel), posters and lamps reported as 'detached' because they sit on parts in other groups, and a scale heuristic that expects a 1 m object. plan-check rejects only the hyphenated library part ids, because its regex allows no hyphen in the first segment. A de-hyphenated copy of the plan passes.

About the Billboards 3D model

Billboards is a free low-poly 3D model from the Highway and Roadworks set. It measures 6.3 m × 6.8 m × 2.6 m (W × H × D) at real-world scale and is built from 690 triangles across 22 meshes, with 8 named parts. Download the 67 KB GLB and drop it into three.js, React Three Fiber, Godot or Blender — free for commercial use, no attribution required.
