Is the Tug 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), 342 KB: 3,874 triangles, 7,352 vertices and 43 materials, modelled in metres at 10 m × 13 m × 25 m.

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 Tug 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.

Tug

A low-poly 24 m harbour tug with a sea blue hull, black rubber fenders, a wide wheelhouse, twin yellow funnels and a towing winch on the aft deck. It loops a 4 s animation: the radar turns, the fire monitor sweeps, the winch drum turns, and the azimuth thrusters swivel as their propellers spin.

How it was made

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

Tug for the Shipping Port 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 Shipping Port kit (Low-poly style, flat-lowpoly direction): Containers, cranes and salt air. Use ONLY the kit palette, by name: container colours #988e81, steel grey #757e8a, sea blue #2e67b8, yellow #eecd2b, container colours dark #70685c, steel grey dark #525860, container colours light #b6b3af, steel grey light #a3a5a8, 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 `containerColoursAndLogos` (0–1, default 0.5) for the kit's "Container colours and logos" setting wherever it makes sense on this part, and keep that id.

Note: Size: the hull is 24 m long with a 9.2 m beam (10.0 m over the fender belt), and 25.3 m overall including the bow and stern cylinder fenders. The main deck is about 3.5 m above the keel aft and rises to the bow. The radar scanner is the highest point at 12.61 m. Origin: x and z are centred on the footprint, y = 0 is the bottom of the keel amidships, and the bow faces +Z. No water is included. The design waterline is 2.6 m above the keel, at the warm white boot top. The azimuth thrusters hang below the stern hull and clear y = 0 by about 5 cm. The GLB has 3,874 triangles in 43 meshes (merged per part and colour) and one 4 s seamless clip, 'scene-motion'. In the clip, the radar turns twice about its pedestal, the fire monitor sweeps ±34° about its swivel, the winch drum turns once about its axle, and each thruster swivels ±20° about its vertical stock while its propeller spins 6 turns about the shaft. The hull never moves. Every material is named exactly after a kit palette colour, and 10 of the 12 appear at the default. A tug carries no containers, so containerColoursAndLogos (the kit's 'Container colours and logos') picks the operator livery for the funnels and deckhouse stripe instead. It steps through container colours light, container colours, yellow (the 0.5 default), sea blue and container colours dark. No logos or text are drawn. The red/green sidelights are stand-ins: sea blue to starboard and container colours dark to port, because the palette has no red or green. Params are baked into the GLB at their defaults and change the geometry only when the scene is rebuilt in the viewer. Both extremes (all-min and all-max) passed three-check. glb-lint: 0 errors and 5 heuristic warnings, all expected: more than 10 material slots and duplicate-material sets (one material per mesh, 10 unique names), bounding-box overlap between nested parts such as the deck, deckhouse and wheelhouse, 'detached' heuristics because each part is one merged mesh, 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. three-check and the GLB keep all 17 ids. Three fix rounds, all visual: a fuller, bluff tug bow (twice) and the hero, front and side framing.

About the Tug 3D model

Tug is a free animated low-poly 3D model from the Shipping Port set.
