Is the Palace 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), 404 KB: 5,252 triangles, 15,756 vertices and 42 materials, modelled in metres at 30 m × 11 m × 28 m.

Can I animate Palace?

It ships as a static mesh. Its 11 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 Palace 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.

Palace

A low-poly Aztec lord's palace: a whitewashed courtyard palace with a pillared portico, a feather-red dado, a carved turquoise frieze and a crest of stepped merlons, set on a talud-tablero platform with a front stair between serpent-headed balustrades. A raised upper hall stands on the back wing, and a pool with jade trees fills the open courtyard.

How it was made

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

Palace for the Aztec Temple City 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. This is one part of the Aztec Temple City kit (Low-poly style, flat-lowpoly direction): A city on a lake with stepped pyramids. Use ONLY the kit palette, by name: stone grey #757e8a, turquoise #31c4b8, feather red #c32222, jade #389475, stone grey dark #525860, turquoise dark #22877e, stone grey light #a3a5a8, turquoise light #6dd5cc, 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 `carvingColour` (0–1, default 0.5) for the kit's "Carving colour" setting wherever it makes sense on this part, and keep that id.

Note: Size: the platform is 30 m wide (x) and 24 m deep, 2.2 m high. The front stair projects about 3.9 m, so the footprint is 30 m by 27.9 m. The palace walls stand 4.2 m on the platform, and the upper hall's merlons top out at 11.19 m. The stair faces +Z, and the origin is at the bottom centre of the footprint, resting on y = 0. The exported model has 5,252 triangles in 42 meshes (merged per part and colour) and no animation clip. Normals are baked flat (non-indexed). All 12 kit colours are used, and every material is named exactly after its palette colour. The exporter may write one material per mesh, so the same colour name can appear on several materials: recolour by name. carvingColour (the kit's 'Carving colour') repaints the frieze band round every wing, the dado caps at the stair head and the serpent heads, in steps: stone grey light (bare) → turquoise light → turquoise (default) → jade → feather red. Params are baked into the GLB at their defaults and only change geometry when the scene is rebuilt in the viewer. width resizes the wings and the courtyard, platformHeight changes the step count, and upperHall removes the raised back hall. The param extremes were checked by reading the geometry limits, not by a capture. Doorways are opaque dark panels with no interiors behind them. glb-lint: 0 errors and 6 heuristic warnings: material count and duplicates, unindexed geometry (flat shading on purpose), sibling overlap (bands and trims embedded on purpose), a 'detached' roofline mesh (the merlons are embedded 2 cm into the roof slabs of the wing parts) and scale (compared with the direction's 1 m reference). plan-check passes except for its part-id regex, which rejects the hyphens this library's slug-based ids need; the same plan with the slug de-hyphenated passes. three-check accepts those ids, and all 11 survive the GLB reload.
