Backrooms to Poolrooms

Walk a liminal loop from the humming yellow maze through dead offices and a shuttered mall to still poolrooms and an empty parking level.

About

A 40 by 30 m interior loop across four zones: the yellow backrooms maze in the west, a dead office and mall strip in the middle, tiled poolrooms in the east and an empty parking level along the south. Spawn faces the backrooms starter block under buzzing fluorescent tiles, then the walk runs east past cubicles, shuttered storefronts and a static escalator, round the pool basin and back west along the parking drive lane to the elevator, stairwell and hotel corridor.

Placed: all 94 pack designs. Backrooms walls, corners, T junctions, alcove, niche, doorways, vent, outlet, pillar, crawlspace grille, broken opening, carpet, damp and pooled floors, drop, plain, fluorescent, air return and skylight ceilings, troffers, office cubicles, desks, chairs, cabinets, cooler, mall floors, storefronts, shutters, columns, benches, planters, kiosk, tables, vending machine, payphone, fountain, signs, escalator, balustrades, pool walls, corners, deck, basin edges and corners, pool floor, water, ladder, entry step and stair, starting block, drain, arch, pillar, bench, shower walls, waterfall lip, rubble, tunnel, deck foundation, parking floors, line tiles, pillars, ramp, bumps, wheel stops, bollards, ticket barrier, pipe run, cable tray, sodium lamps, elevator doors and car, hotel walls, doors and ice alcove, emergency lights, handrails, stair flight and landing, fire door, half walls, backroom ramp, descending stair and the three starter scenes. The pipe run and cable tray sit at floor level as trunking because every model in this pack is ground based and nothing may float.

Movement: nothing moves. The pack ships zero animation clips, so every placement uses the default static pose and no animate flag is set. That stillness is the point of a liminal space: fluorescent lights that cannot flicker and water that cannot ripple.

Not placed: nothing. Every design in the members list appears at least once.

Every piece here is a published model from the pack, placed by hand. Walk with the keys or touch, and approach a piece to see it move if it has animation. Colliders, navigation and gameplay are yours to add.

The dead mall
Shuttered storefronts, an empty kiosk, a silent payphone and a static escalator that goes nowhere. The food court tables wait for a crowd that left.

The poolroom hall
The tiled hall opens onto the basin: starting block, entry arch, ladder rails and a waterfall lip over still water. Skylight modules light the west deck.

Common questions

How do I use Backrooms to Poolrooms with my AI development tools?

Press "Copy for AI agent" above and paste the prompt into Claude Code, Cursor, Codex, GitHub Copilot, ChatGPT or any other coding assistant. The prompt carries the direct CDN URL, the real-world size, the licence and the loading notes, so the assistant can fetch the scene and place it in your project without you writing the loader yourself. For a permanent connection, add the 3DAssets.dev MCP server to your tool with one command (for Claude Code: claude mcp add --transport http 3dassets https://3dassets.dev/mcp) and the assistant can then search the whole catalogue, fetch files and read the usage snippets on its own.

MCP server setup Guide for AI agents

How do I get started?

Walk the scene here with the keys or touch to see how the pack fits together. To build it yourself, download the pack with the button, then copy the "Copy for AI agent" prompt: it links the layout JSON, which lists every placement with its position, rotation and CDN URL, so an assistant connected to the MCP server can rebuild the scene in your engine and change it to order.

MCP server setup

Which game engines and tools can I use Backrooms to Poolrooms with?

Anything that reads glTF, which today means all of the major ones: three.js and React Three Fiber on the web, Godot 4, Unity, Unreal Engine 5, Blender and the model-viewer web component. Every model in the scene is a self-contained binary glTF (.glb) with textures embedded, so each is one file to import and no plugin, converter or decoder to install first.

How do I import this scene into Unity, Godot, Unreal or Blender?

Unity: install the glTFast package (com.unity.cloud.gltfast) from the Package Manager, drop the .glb into Assets and drag the prefab in, or load it at runtime from the CDN URL. Godot 4: copy the file into the project folder and the editor imports it as a scene you can instantiate. Unreal Engine 5: File > Import with the built-in glTF importer, which converts the axes for you. Blender: File > Import > glTF 2.0. Units are metres with +Y up in the file, and every importer above handles the conversion to its own axes automatically.

Can I use Backrooms to Poolrooms in a commercial game, and do I need to credit anyone?

Yes to commercial use and no to credit. Every scene on 3DAssets.dev is released under CC0 1.0 Universal, which places it in the public domain: use it in a paid game, an app, a film or a client project, modify it, redistribute it, and put nothing in the credits. A link back is welcome but it is entirely your choice.

CC0 licence text

Can I load it from the CDN instead of downloading it?

Yes. The pack behind it has a permanent URL on cdn.3dassets.dev that is CORS-enabled and never changes content, so you can pass it straight to GLTFLoader, glTFast or model-viewer in production and cache it as hard as you like. Downloading is only needed for engines that import from disk.

Is the demo itself a file I can download?

No, and it does not need to be. A demo is a layout of the pack's published models composed in your browser from the CDN, so there is no extra file to fetch. Download the pack for the models, and take the layout JSON linked above for the placements: together they are the whole scene, and an AI agent can rebuild it from those two links.

Can I change the scene, or add gameplay to it?

Yes. The layout is plain data in metres, so move, add or remove placements freely in your own engine. Colliders, navigation and gameplay are yours to add: the demo shows what the pack looks like assembled, and your game decides how it plays.
