Is the Hill 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), 500 KB: 6,958 triangles, 20,862 vertices and 11 materials, modelled in metres at 4.0 m × 2.6 m × 4.0 m.

Can I animate Hill tiles?

It ships as a static mesh. Its 9 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 Hill 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.

Hill tiles

A low-poly 4 x 4 m ground tile with a faceted grassy knoll, a gravel footpath up its flank, a rock outcrop on the crest and a red-and-white windsock on the summit. Its flat edges tile flush with neighbouring ground pieces.

How it was made

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

Hill tiles for the Wind and Solar Farm 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 Wind and Solar Farm kit (Low-poly style, flat-lowpoly direction): Clean power on open land. Use ONLY the kit palette, by name: white #f4f1ec, panel blue #2e67b8, grass green #3a883a, signal red #e90c0c, white dark #d7cebc, panel blue dark #1f457a, white light #f9f8f6, panel blue light #6190d1, 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 `windSpeed` (0–1, default 0.5) for the kit's "Wind speed" setting wherever it makes sense on this part, and keep that id.

Note: Size: an exact 4 x 4 m footprint, with the origin at the tile centre and the bottom on y = 0. The knoll crest is about 1.25 m above the base and the windsock pole tops out at 2.61 m. Every border sits flat at 0.10 m (a 0.05 m dark soil bed under 0.05 m of grass), so the tile meets any flat neighbour flush on all four sides, and nothing crosses the edge. Units are metres, +Y up and the front faces +Z. The GLB has 6,958 triangles in 11 meshes. It is static and carries no animation clip. Every material is named exactly after a kit palette colour (7 of the 12). The exporter writes one material per mesh, so some names repeat: recolour by name. windSpeed (the kit's 'Wind speed') is a pose, not motion. The sock hangs limp at 0 and streams level at 1 (about 39 degrees below level at the default 0.5), and the grass tufts lean further downwind as it rises. The sleeve is its own part (windsock_sock), pivoted at the swivel. Params are baked into the GLB at their defaults and only change geometry when the viewer rebuilds the scene. glb-lint reported 0 errors. Its warnings are expected: one material per mesh, non-indexed geometry for hard flat facets, rocks nested into the hill, and a 'scale' heuristic that expects 1 m objects. plan-check rejects only the hyphenated library part ids, because its regex allows no hyphen. The same plan with the slug de-hyphenated passes, and three-check and the GLB reload keep all 9 ids.

About the Hill tiles 3D model
