Walkable demo

Summit push

Walk a 64 by 72 metre guided expedition from the Mountaineering and Summit Expedition pack: base camp on moraine, a laddered glacier traverse, fixed rope ridge and a summit cairn.

About

One expedition from 49 of the pack's 50 models, in the outdoor preset with day light.

You start at the base camp gate facing the mess row across moraine tiles: dome, bivouac and assault tents inside stone wind walls, the kitchen and mess tents with camp tables, stools, stove sets, solar panels and supply caches, and porters staging packs, haul bags, rope coils, helmets, boots and oxygen sets. Wand lines lead north to the glacier traverse of six crevasse modules bridged by ladders, with fixed rope anchors, snow bollards, ice screws and a roped team crossing beside serac blocks, the rescue sled and the icefall wall on the west flank.

Past the bergschrund lip the route connector ramp climbs between snow and corniced ridge modules with anchors, wands and bollards all the way, the fixed rope climber ascending while the belayer holds, the lead climber working the rock band step, up to the summit ridge massif with its cairn, the down suit summiteer, spare oxygen, summit packs and the flag line.

Nothing moves: this pack ships without animation clips, so every figure is posed with animate off and the ladders, ropes and sleds rest as placed. The ground is a flat datum and the terrain modules carry their own height, with the ladders set onto the crevasse module tops.

Not placed: the Base camp on moraine starter scene, because the demo hand builds its own base camp from the same tents and gear so the walk reads as one continuous route from camp to summit.

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 Summit push 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 Summit push 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 Summit push 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.
