Is the Reptile house 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), 319 KB: 3,946 triangles, 11,838 vertices and 46 materials, modelled in metres at 4.0 m × 4.1 m × 4.0 m.

Can I animate Reptile house?

It ships as a static mesh. Its 12 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 Reptile house 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.

Reptile house

A low-poly zoo reptile house on a 4 × 4 m ground tile: a stucco pavilion with a green gable roof and roof lights, a timber double door under a yellow lizard sign, and two vivarium windows, one desert and one jungle. A big faceted iguana sprawls along the ridge, and the forecourt planting shifts from desert cacti and rocks to a palm and ferns.

How it was made

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

Reptile house for the Zoo 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 Zoo kit (Low-poly style, flat-lowpoly direction): Enclosures and winding paths. Use ONLY the kit palette, by name: leaf green #3a883a, sand #d1bd94, timber #765232, sign yellow #eecd2b, leaf green dark #235223, sand dark #ba9c5e, leaf green light #5db15d, sand light #e6ddcb, 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 `habitatMix` (0–1, default 0.5) for the kit's "Habitat mix" setting wherever it makes sense on this part, and keep that id.

Note: Size at default params: an exact 4.00 × 4.00 m tile, 4.12 m tall to the iguana's crest. The house is 3.0 m wide (X) and 2.3 m deep (Z), with 2.3 m walls on a 0.28 m plinth and the roof ridge at about 3.8 m. Metres, +Y up, front faces +Z, origin at the tile centre, bottom on y = 0. How it tiles: the ground top is flat at 0.10 m on all four edges, the same border height as the kit's path tiles. Nothing crosses or overhangs the footprint, and the lawn/sand patch pattern repeats every 4 m. The exported model has 3,946 triangles in 46 meshes, one mesh per palette colour per part. All 12 kit colours are used, and every material is named exactly after its palette colour. The exporter writes one material per mesh, so a name repeats across materials; recolour by name. Flat-shaded, metalness 0, no textures, no text. Static: no animation clip. Panes are opaque soot-black facets, not transparent glass. habitatMix (the kit's 'Habitat mix') changes the geometry. It sets which ground cells are lawn or sand, what grows at each fixed seeded spot (rocks and cacti, or bushes and ferns), and what each vivarium shows. At 0.5 the left window is jungle and the right is desert, and the front corners carry a palm and a saguaro. All params rebuild the model in the viewer; the GLB carries the default values. Hierarchy: each part is a node named zoo-reptile-house.<part> (extras.partId = that id). It holds one child named zoo-reptile-house.<part>.geo with the meshes. The .geo nodes carry a mirror id zooreptilehouse.<part> in extras.partId because the design kit's plan validator rejects hyphenated ids; you can ignore them. glb-lint: 0 errors. Its overall verdict is UNVERIFIED only because no requirements contract was supplied. Its 5 heuristic warnings were reviewed in the captures: material count (one per mesh, as above), non-indexed primitives (intentional flat shading), sibling overlaps (trim, frames and panes seated on the walls are deliberate embedded joins), and a 4.12 m height against the 1 m reference (true scale). In the hero preview the nearest front tile corner touches the bottom edge of the frame.
