Is the Flashing signs 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), 231 KB: 2,592 triangles, 7,776 vertices and 33 materials, modelled in metres at 2.3 m × 3.7 m × 3.1 m.

Is Flashing signs animated?

Yes — the GLB carries a baked animation (4.0 s), ready to play with any glTF animation mixer.

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 Flashing signs 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.

Flashing signs

A low-poly roadworks arrow board on a single-axle trailer. The orange-rimmed black lamp board sits on a braced mast above an orange battery box with a solar panel. Its arrow lights in a looping tail-to-head chase between two spinning amber beacons.

How it was made

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

Flashing signs 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. It moves: author a seamless baked loop (2–12 s) with every pivot exactly at its hinge, axle or swivel, and keep the base still. 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: about 2.6 m wide (X), 3.1 m long from hitch to tail (Z) and 3.74 m tall at the default params. The lamp face looks toward +Z and the drawbar points to -Z. The origin is at the bottom centre of the footprint, and the tyres, jockey wheel and jack pads rest on y = 0. The GLB is baked at the default params: 2,592 triangles in 33 meshes, with one seamless 4 s clip. In each 1 s cycle the whole arrow is lit, goes dark, then lights tail, middle and head 0.25 s apart. A dark lamp group slides 12 cm back inside the board, so the clip uses translation only. The two beacon rotors spin about their own spindles, four turns per loop, in opposite directions. The trailer, mast and board never move. Every material is named after its kit palette colour, so you can recolour by name. The exporter writes one material per mesh, so some names repeat. The lit lamps are flat warm-white discs, not light sources. Country road rules (the kit's knob): towards 1 the board shrinks from 2.6 x 1.4 m (motorway) to 1.9 x 1.05 m (country lane) and the mast lifts it less. mastRaise and arrowRight (flips the arrow to point right) rebuild the model in the viewer only. glb-lint: 0 errors, plus expected heuristic warnings: the lit lamp discs flag as detached because they sit in hoods that belong to another part; there are also duplicate palette names, non-indexed flat-shaded geometry, nested overlaps and a 1 m scale heuristic. It ends 'UNVERIFIED' only because no requirements contract is supplied. 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 Flashing signs 3D model

Flashing signs is a free animated low-poly 3D model from the Highway and Roadworks set.
