Is the Galleries 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), 189 KB: 2,108 triangles, 6,324 vertices and 48 materials, modelled in metres at 8.3 m × 4.4 m × 8.9 m.

Can I animate Galleries?

It ships as a static mesh. Its 22 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 Galleries 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.

Galleries

A low-poly cutaway museum gallery room with deep red walls hung with brass-framed paintings, a chequered marble floor and a central bench. A roped-off marble arch leads into a small niche gallery holding an urn on a plinth.

How it was made

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

Galleries for the Museum 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 Museum kit (Low-poly style, flat-lowpoly direction): Quiet halls of old things. Use ONLY the kit palette, by name: marble white #f4f1ec, deep red #861313, brass #b28c34, slate #525e6f, marble white dark #d7cebc, deep red dark #430a0a, marble white light #f9f8f6, deep red light #c32222, 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 `collectionTheme` (0–1, default 0.5) for the kit's "Collection theme" setting wherever it makes sense on this part, and keep that id.

Note: Size: 8.30 m wide (X), 4.36 m tall (Y) and 8.86 m deep (Z). That is the room plus the niche behind the back wall. The room interior is 7.4 m wide and 6.7 m deep, with 4.0 m walls standing on a 0.2 m floor slab. The side walls stay full height for the back 58% of the room, then step down to a 1.05 m wall at the open front, so the interior can be seen from every orbit angle. There is no ceiling. The origin is at the bottom centre, the slab rests flat on y = 0, and the open front faces +Z. The GLB has 2108 triangles and carries no animation or textures. Every material is named exactly after a kit palette colour; the default theme uses all 12. The runtime's exporter writes one material per mesh, so the same colour name appears on several materials (48 in total). Recolour by name. The paintings are flat two-tone colour blocks with no imagery or text. Some parts touch or overlap on purpose: the marble tiles stand 12 mm proud of the slab, the skirting and stanchion bases sit on the floor top, and the exterior pilasters and base course are partly buried in the walls. These are deliberate joins, not floating gaps, and no visible faces are coplanar. Params are baked at their defaults and only change the model when the scene is rebuilt in the viewer. collectionTheme (the kit's 'Collection theme') sets the hang: below 0.33 is an archive look (slate walls and slab, brass frames); 0.33–0.67 (default) is a classical salon (deep red walls, brass frames, grey and white chequer); above 0.67 is a modern gallery (warm white walls, soot black frames, urn and rope). Only the default params were rendered and checked. glb-lint reports 0 errors and 6 warnings: material count and duplicate materials (both from the per-mesh clones), non-indexed geometry (deliberate flat shading), sibling overlaps (the deliberate buried joins), detached parts (the cornice, niche cornice and bench cushion rest face-to-face on parts in other groups), and scale (a 4.36 m room against the direction's 1 m reference). Its verdict reads UNVERIFIED only because no host requirements contract was supplied. plan-check passes except for its part-id regex, which rejects the hyphen in the slug-based ids this library requires; with the ids substituted it passes. three-check accepts the real ids, and all 22 survive the GLB reload.
