Is the Junction) 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), 86 KB: 1,100 triangles, 3,288 vertices and 10 materials, modelled in metres at 16 m × 2.7 m × 16 m.

Can I animate Junction)?

It ships as a static mesh. Its 6 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 Junction) 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.

Junction)

A low-poly 16 × 16 m road tile with a two-lane T-junction. A main road crosses the tile and a side road joins it from the front through faceted kerb corners. It has white centre dashes, a give-way line and triangle on the side road, four orange roadworks cones and a green direction sign facing the side road.

How it was made

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

Junction) 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: exactly 16.00 × 16.00 m footprint and 2.70 m tall at the top of the sign. The road deck stands 0.16 m high and the grass verge 0.12 m. The origin is at the tile centre, the bottom rests on y = 0 and the front faces +Z. The main road runs along X and leaves the −X and +X edges. The side road leaves the +Z edge. Each road end is centred on its edge and square to it, with the same cross-section as the kit's Curve tile: two 3.5 m lanes plus 0.5 m hard shoulders at the default. The main centre dashes keep the Curve tile's 4 m rhythm, with half gaps at the tile edges. The kerb corners are 8-facet fillets. The give-way markings sit on the side road's inbound lane for right-hand traffic. For left-hand traffic, mirror the tile on X. The cones are 0.75 m tall and the sign panel is 2.4 × 1.6 m with a T-junction pictogram, no text. The GLB is baked at the default params and has 1,100 triangles in 10 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 'line white' appears three times (markings, cone bands, sign) and 'sign green' twice (verge, sign face). Country road rules (the kit's knob): at 0 you get motorway rules, with 1 m hard shoulders, solid edge lines that follow the kerb corners and short centre dashes. Towards 1 you get a country lane: the shoulders shrink to nothing (gone above 0.95), the edge lines drop out from 0.75 and the dashes stretch into a long hazard line. laneWidth, kerbRadius and cones rebuild the tile in the viewer only. Both extreme combinations were rendered and passed three-check, but only the defaults are exported. glb-lint: 0 errors and 5 heuristic warnings, all expected: duplicate palette materials (one per mesh); non-indexed flat-shaded geometry; overlapping bounding boxes for the shoulders and carriageway and for the cone bodies and bands, which interlock by design; and the markings and cone bases sit on the deck rather than on y = 0, so they register as 'detached'; 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, and three-check and the GLB carry all 6 ids correctly.

About the Junction) 3D model

Junction) is a free low-poly 3D model from the Highway and Roadworks set.
