## About

Run of eighteen heavy chain links lying interlocked in a slack curve about 2.9 m long, half sanded over. Dimensions 3.20 by 0.28 by 1.96 m (X by Y by Z). Metre units, +Y up, +Z front, origin on the footprint at seabed level. Modelled solid in one piece: a chain needs a joint per link, which a single rigid node transform cannot give, so it does not move. Sunken city palette: weathered grey limestone and dark algae stained stone, pale silt, deep green weed, coral pink, waterlogged timber, tarnished bronze and one translucent blue emissive for glow, bubbles and light. Static geometry; no rig, animation, collision or navigation data.

## Use with three.js

```js
import { GLTFLoader } from 'three/addons/loaders/GLTFLoader.js'

const loader = new GLTFLoader()
loader.load('https://cdn.3dassets.dev/assets/36977/v1/model.glb', (gltf) => {
  scene.add(gltf.scene)
})
```

## React Three Fiber

```jsx
import { useGLTF } from '@react-three/drei'

export function ChainRunSunkenCityAndUnderwaterRuins(props) {
  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/36977/v1/model.glb')
  return <primitive object={scene} {...props} />
}
useGLTF.preload('https://cdn.3dassets.dev/assets/36977/v1/model.glb')
```

<model-viewer src="https://cdn.3dassets.dev/assets/36977/v1/model.glb" alt="Chain Run (Sunken City and Underwater Ruins)" camera-controls auto-rotate></model-viewer>
```

## Blender

```python
# Blender 4.x: File > Import > glTF 2.0, or from the Python console after downloading the file.
import bpy
bpy.ops.import_scene.gltf(filepath='model.glb')  # from https://cdn.3dassets.dev/assets/36977/v1/model.glb
# Metres and +Y up are converted to Blender's Z-up scene automatically.
```

## Godot

```gdscript
# Godot 4: copy model.glb into res://models/ and the editor imports it as a scene.
var packed := load("res://models/model.glb") as PackedScene
var model := packed.instantiate()
add_child(model)
```

## Unity

```csharp
// Unity: import model.glb with glTFast (Package Manager: com.unity.cloud.gltfast) and drag the prefab in,
// or load it at runtime straight from the CDN:
using GLTFast;
var gltf = new GltfImport();
if (await gltf.Load("https://cdn.3dassets.dev/assets/36977/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
```
