Is the Barriers 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), 119 KB: 1,536 triangles, 4,608 vertices and 12 materials, modelled in metres at 6.1 m × 2.1 m × 62 cm.

Can I animate Barriers?

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 Barriers 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.

Barriers

A low-poly run of three interlocking concrete Jersey barriers painted with launch-orange hazard stripes, topped by a steel security fence with outward-leaning barbed-wire arms and orange range beacons — the exclusion-zone perimeter of a coastal launch site.

How it was made

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

Barriers for the Rocket Launch Site 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 Rocket Launch Site kit (Low-poly style, flat-lowpoly direction): Countdown at the coast. Use ONLY the kit palette, by name: white #f4f1ec, launch orange #ed7e1d, steel #7e8c9a, sky blue #2e67b8, white dark #d7cebc, launch orange dark #af590e, white light #f9f8f6, launch orange light #eea668, 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 `rocketDesign` (0–1, default 0.5) for the kit's "Rocket design" setting wherever it makes sense on this part, and keep that id.

Note: Size: 6.08 m long (X) × 0.62 m deep (Z) × 2.09 m tall to the beacon tops; each segment is 2.0 m long and 0.81 m high on a 0.6 m Jersey safety-shape base, with a 1.0 m fence above and 0.42 m barbed-wire arms leaning 45° toward +Z (the public side). Origin at the bottom centre of the run, resting on y = 0. Static: no animation clip. The GLB is baked at the default params: 1,536 triangles in 12 meshes, non-indexed with flat normals on purpose. Every material is named exactly after its kit palette colour (5 of the 12 kit colours are used); the exporter writes one material per mesh, so names repeat — recolour by name. rocketDesign (the kit's Rocket design knob) sets the hazard livery: 2 broad stripes per face at 0, 4 at the default, 6 narrow ones at 1. segmentCount, segmentLength and fenceHeight rebuild the model in the viewer only. The extreme (rocketDesign 1, 5 × 1.5 m segments, 1.4 m fence) also passed three-check. glb-lint: 0 errors and 6 heuristic warnings, all expected — material count/duplicates (one material per mesh), unindexed flat-shaded geometry, nested overlaps (stripes and couplers sunk into the concrete), fence/wire/stripes counted as 'detached' because they socket into another part, and a scale heuristic expecting a 1 m object. plan-check rejects only the hyphenated library part ids (its regex allows no hyphen in the first segment); the same plan with the slug de-hyphenated passes, and three-check and the GLB carry all 7 ids.

About the Barriers 3D model

Barriers is a free low-poly 3D model from the Rocket Launch Site set.
