Is the Buoys 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), 87 KB: 1,064 triangles, 3,192 vertices and 14 materials, modelled in metres at 1.7 m × 3.9 m × 1.7 m.

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 Buoys 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.

Buoys

A low-poly 3.85 m steel pillar mooring and marker buoy for the Fishing Harbour kit. It has a faceted sea-blue float hull with a darker wet band below the waterline, a black fender ring, a white lattice tower, an amber lamp and a black topmark, on a ballast tail with a mooring eye.

How it was made

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

Buoys for the Fishing Harbour 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 Fishing Harbour kit (Low-poly style, flat-lowpoly direction): Boats, nets and a sea wall. Use ONLY the kit palette, by name: sea blue #2e67b8, boat colours #988e81, rope tan #bf9769, grey stone #9c958b, sea blue dark #1f457a, boat colours dark #70685c, sea blue light #6190d1, boat colours light #b6b3af, 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 `tide` (0–1, default 0.5) for the kit's "Tide" setting wherever it makes sense on this part, and keep that id.

Note: Size: 3.85 m tall from the counterweight underside to the topmark tip, 1.80 m across the fender ring. The float hull is 1.6 m across the facet corners, and the deck is at 1.65 m. The origin is on the buoy axis at the counterweight's underside, and the model rests on y = 0 (GLB bounds y 0.000–3.850), with the mooring eye facing +Z. It is shown standing out of the water on its counterweight, as on a quay or in a buoy yard. No water or chain is included. tide (the kit's 'Tide') moves the waterline from 0.86 m to 1.18 m up the hull. Paint below the line is the wet sea blue dark, and a warm-white boot-top stripe marks the line. It changes paint only, not the geometry. towerHeight (0.8–1.8 m) sets the lattice tower height. legCount switches between a 3-leg and a 4-leg tower, and the lifting eyes follow the gaps between the legs. topmark picks a can, cone (default) or ball. The GLB has 1,064 triangles in 14 meshes (counted from the GLB accessors), is static and carries no animation clip. Normals are baked flat (non-indexed). three-check's ~1.35k figure includes the viewer's staging ground, which is not exported. Every material is named exactly after a kit palette colour, and 7 of the 12 are used. The exporter writes one material per mesh, so a colour name can appear on several materials; recolour by name. Params are baked into the GLB at their defaults and change the model only when the scene is rebuilt in the viewer. Both extremes rendered and passed three-check with all 8 part ids: all-min (tide 0, 0.8 m tower, 3 legs, can topmark) and all-max (tide 1, 1.8 m tower, 4 legs, ball topmark). glb-lint: 0 errors and 6 heuristic warnings, all expected. They cover more than 10 materials and duplicate names (one material per mesh), non-indexed flat shading, the lens nested in the lamp, 'detached' heuristics for the fender and topmark (they rest on meshes in other parts), and the scale check for a subject taller than 1 m. plan-check rejects only the hyphenated library part ids, because its regex allows no hyphen; the same plan passes with the slug de-hyphenated. Scene head and merge adapted from the shipping-port-drums library asset. One fix round, visual only: the fender moved up to the hull's top edge, so the waterline stripe no longer stacks into a cluttered band under it.

About the Buoys 3D model
