Is the Party room 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), 259 KB: 4,236 triangles, 7,926 vertices and 10 materials, modelled in metres at 6.0 m × 2.9 m × 5.0 m.

Can I animate Party room?

It ships as a static mesh. Its 21 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 Party room 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.

Party room

A low-poly cutaway arcade party room: two glowing arcade cabinets, a big wall screen, a long party table with a tiered cake, benches, gifts, bunting and a tethered balloon bunch on a black confetti carpet.

How it was made

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

Party room for the Arcade 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 Arcade kit (Low-poly style, flat-lowpoly direction): Screens glowing in a dark room. Use ONLY the kit palette, by name: black #151619, neon purple #9123c7, cyan #20c6df, hot pink #f589ad, black dark #090a0b, neon purple dark #611886, black light #3a3c40, neon purple light #b15bdc, 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 `era` (0–1, default 0.5) for the kit's "Era" setting wherever it makes sense on this part, and keep that id.

Note: Real-world size at default params: 6.0 m wide × 2.87 m tall × 5.0 m deep (walls 2.7 m on a 0.12 m floor slab); origin at the bottom centre, front open toward +Z, right side open toward +X. Static model, no animation clip. 4,236 triangles, 10 materials, each named exactly by its Arcade kit palette colour (mid grey and black dark are not used). Cyan, hot pink and neon purple light are emissive so screens, neon and confetti glow. Flat shading is baked into the geometry normals, so the facets survive in Godot, Unity and Blender. Era: 0 gives a deep wood-framed CRT wall screen and tall dark-wood panelling; 1 gives a slim flat panel and a skirting board. Room width/depth re-lay out the furniture, and balloon count adds balloons to the tethered bunch. Every param regenerates geometry; they are not viewer-only. Part ids: real parts use arcade-party-room.*; the three partyroom.* group nodes exist because the kit's plan checker does not allow a hyphen in the root id. glb-lint: 0 blocking errors. Its overall verdict reads UNVERIFIED because no requirements contract was supplied. It raised 3 heuristic warnings: nested per-material meshes, wall-mounted pieces touching a wall in another group, and a room height above the direction's 1 m reference. fixRounds counts 3 visual rounds plus 1 fix found while testing the param range (a gift box cutting into a bench at minimum room size). The project's runtime export was patched so shared materials export once instead of once per mesh.
