Is the Tundra 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), 502 KB: 6,906 triangles, 20,706 vertices and 17 materials, modelled in metres at 4.0 m × 71 cm × 4.0 m.

Can I animate Tundra tiles?

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 Tundra 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.

Tundra tiles

A low-poly 4 × 4 m Ice Age tundra ground tile: hummocky moss and dry-sedge turf with cottongrass tussocks, snow lingering in the hollows, a frost-shattered boulder cluster, dwarf birch and a shed reindeer antler. Every edge is flat, so copies tile seamlessly in every direction.

How it was made

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

Tundra tiles for the Stone Age Camp 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 Stone Age Camp kit (Low-poly style, flat-lowpoly direction): Hide tents at the edge of the ice. Use ONLY the kit palette, by name: hide tan #bf9769, ochre #bd8728, charcoal #34383d, moss #55743e, hide tan dark #9a7142, ochre dark #7e5a1b, hide tan light #d2bca2, ochre light #d6a95c, 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 `climateIceOrForest` (0–1, default 0.5) for the kit's "Climate (ice or forest)" setting wherever it makes sense on this part, and keep that id.

Note: Size: exactly 4.00 × 4.00 m and 0.71 m tall at the defaults (tallest point: the snow cap on the big boulder; tussocks reach about 0.5 m). The bottom rests on y = 0, the origin is at the tile centre and the front faces +Z. The soil bed is 0.05 m thick and the turf sits at 0.10 m at every border. How it tiles: the hummocks fade to the border height within 0.5 m of every edge, so all four edges are flat at the same height and meet any neighbour flush, rotated copies included. The snow, moss and sedge colour fields repeat every 4 m, so the patches carry on across seams between unrotated copies. climateIceOrForest (the kit's 'Climate (ice or forest)') changes colour and props only, never the border height, so tiles at different climates still meet flush. At 0, snow fills most hollows and the boulders wear snow caps. Toward 1, the snow melts away, moss spreads and more dwarf birch appears (1 shrub at 0, 4 at the default, 7 at 1), and from 0.6 the boulder caps turn to ochre-light lichen. hummockHeight scales the turf mounds. tussockCount (0–22) sets how many hummock crowns carry a sedge tussock. Params are baked into the GLB at their defaults and change the geometry only when the scene is rebuilt in the viewer; only the defaults were rendered and checked. The GLB has 6,906 triangles in 17 meshes. It is static, with no animation clip. Every material is named exactly after a kit palette colour, and 10 of the 12 kit colours are used (no soot black or ochre dark). The exporter writes one material per mesh, so names repeat — recolour by name. glb-lint: 0 errors and 5 expected warnings (17 materials > 10 from the per-mesh export, duplicate names, non-indexed geometry kept on purpose for hard flat facets, tussocks nested on the turf, snow/antler 'detached' though both lie on the turf). The lint verdict line reads UNVERIFIED only because no requirements contract was supplied. plan-check rejects only the hyphenated library part ids (its regex allows no hyphen); the same plan with the slug de-hyphenated passes. three-check and the GLB reload keep all 8 ids. Viewer-only staging (ground disc, sun rig, exposure 0.7) is not in the GLB.
