Is the Legs and sea tiles 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), 147 KB: 1,942 triangles, 5,826 vertices and 12 materials, modelled in metres at 4.0 m × 5.0 m × 4.0 m.

Can I animate Legs and sea tiles?

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 Legs and sea tiles 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.

Legs and sea tiles

A low-poly 4 × 4 m open-sea tile with a rust-orange offshore jacket leg standing in a blue-teal swell, braced on all four sides by closed X-brace panels. The waves and the half-posts on the borders line up across tiles, so copies tile into one braced rig substructure, and with the leg switched off it is a plain sea tile.

How it was made

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

Legs and sea tiles for the Oil Rig 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. Make it a ground piece on an exact 4 × 4 m footprint with flat edges at y = 0 that tile seamlessly with its neighbours in every direction; origin at the tile centre. This is one part of the Oil Rig kit (Low-poly style, flat-lowpoly direction): A steel island in rough water. Use ONLY the kit palette, by name: rust orange #ed7e1d, sea grey #757e8a, yellow #eecd2b, white #f4f1ec, rust orange dark #af590e, sea grey dark #525860, rust orange light #eea668, sea 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 `seaState` (0–1, default 0.5) for the kit's "Sea state" setting wherever it makes sense on this part, and keep that id.

Note: Size: an exact 4 × 4 m footprint and 5.0 m tall at the default leg height. The sea slab is 0.7 m deep at mean level. The leg is an octagonal tube 1.2 m across, with a pile-head cap the Platform decks piece can sit on. The origin is at the tile centre, the bottom rests on y = 0 and the front faces +Z. Every border face is a flat vertical plane. Each wave has a whole number of cycles across 4 m, so the surface heights on opposite borders are identical. Bracing: on each side, horizontals run from joint cans on the leg to a panel post at the border midpoint, and every bay between two horizontals has a crossed pair of diagonals. Every member ends in the leg, the post or another member; none ends in open air. Each post is centred on the border and cut flat 1 mm inside it, so two neighbouring tiles' halves close into one post and a grid reads as one braced jacket with a leg every 4 m. On its own, a post shows a flat back face on the tile edge. Palette: the three sea blues (sea blue #1f6f86, sea blue light #7cc3d1, sea blue dark #123f52) are not part of the original 12-colour Oil Rig kit palette. They were added at review because the kit has no water colour and a grey sea read as stone. A kit that recolours strictly by its 12 names will not find them. All other materials use kit colours and every material is named exactly after its colour. Some colours appear on two materials because each part merges its own meshes. The GLB has 1,942 triangles in 12 meshes and no animation clip; it is a static asset. Params are baked into the GLB at their defaults and change the geometry only when the scene is rebuilt in the viewer. leg = 0 gives a plain sea tile. braceLevels sets the number of braced bays (1 to 3), which means 2 to 4 horizontal rings. seaState (the kit's 'Sea state') sets the wave height (0.03 to 0.18 m), the pale crest facets (none below 0.1) and the width of the foam ring. Extremes were checked with three-check and both passed: leg height 8 m / 3 bays / sea 1, and leg height 4 m / 1 bay / sea 0. glb-lint: 0 errors. Its verdict prints UNVERIFIED because 5 rules need a requirements contract or a manual review. Its 6 warnings were reviewed and do not apply: the meshes are non-indexed for flat shading, there are 12 materials because colours repeat per part, the leg passes through the sea on purpose, the cap and pad sit on the leg, and a 5 m height is expected for a rig leg. plan-check passes except for its part-id regex, which rejects the hyphens in the slug-based ids this library requires. A copy with the hyphens removed passes, and three-check accepts the ids.
