Space station

Walk an orbital assembly yard from the Orbital Station and Docking Bays pack: an eighteen-element pressurised cluster with a ferry and freighter berthed, a 41 m truss with solar wings and radiators, robot arms, EVA crew, a cargo line and an open interior bay.

About

One assembly yard from 52 of the pack's 60 models, in the space preset: a star field all round, a banded gas giant low on the horizon with its moon, hard white sunlight and no ground at all.

You start beside the docked crew ferry and walk along the research laboratory to the forward node, where the logistics module and the airlock meet it. Two connecting tunnels lead through the six-port hub, with the cupola on its nadir and the dexterous manipulator on its zenith, to the aft node: the habitation module and the service module aft, the gold blanket habitation module to starboard with a berthing mechanism and soft capture ring on its free end, and the expandable habitat to port. The cargo freighter is berthed on the hub starboard hatch; the transfer tunnel on the port hatch carries the compact laboratory, which ends in an open androgynous docking port where the propellant tanker holds 7 m out on approach with two crew on manoeuvring units.

Overhead a 41 m truss of nine bays and two rotary joints ends in a deployed solar wing each side, with four deployed and two stowed radiators in a row on its back, and the mobile base cart with the second manipulator arm, an external stowage platform with a stowed array canister, the high gain dish, experiment platforms, antennas and camera arms on top. Handrails run every module flank at hatch height. On the yard floor the starboard cargo line holds platforms, thruster quads, radiators, a rotary joint and spare docking hardware; the port side has camera masts marking the approach corridor and a 13 m interior bay laid open, with racks in two liveries, gloveboxes, sleep stations, exercise device, hygiene stalls, stowage walls, duct runs and suits on stands.

Nothing moves: this pack ships without animation clips, so the wings, the radiators and the arms are static. Orbit, microgravity and the module interiors are yours to add; the modules are closed shells. Four of the pack's fittings are not placed: the hinged hatch cover, the portable foot restraint, the latching end effector and the robotic grapple fixture, which read as nothing at yard scale.

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.

Common questions

How do I use Space station 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.

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 Space station 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 Space station 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.
