## About

Chain lift section of steel coaster track climbing at 30 degrees: a chain trough between the rails, a run of chain dogs on their own node and a line of anti rollback ratchet teeth. Free 3D model for theme park, roller coaster and tycoon game scenes in Unity, Godot, Unreal, three.js and Blender. Overall 1.06 by 2.43 by 3.71 m (X by Y by Z). Metre units, +Y up, +Z forward. Pivot on the grid origin at the mid point of the climb; port a is the low end. Stack the piece to build a lift of any height. Rigid node-transform clips: chain-open and chain-close. No skinning. The ratchet teeth, the chain trough and the return chain under the spine are modelled solid: only the chain dog run carries a node, and it travels one link pitch along the section rather than round a real loop.

## Use with three.js

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

let mixer

const loader = new GLTFLoader()
loader.load('https://cdn.3dassets.dev/assets/28629/v1/model.glb', (gltf) => {
  scene.add(gltf.scene)
  mixer = new AnimationMixer(gltf.scene)
  mixer.clipAction(gltf.animations[0]).play()
})

// Call from your render loop; deltaSeconds is time since the previous frame.
function updateAssetAnimation(deltaSeconds) {
  mixer?.update(deltaSeconds)
}
```

## React Three Fiber

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

export function CoasterLiftHillSectionThemeParkRidesAndCoasters(props) {
  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/28629/v1/model.glb')
  const { actions, names } = useAnimations(animations, scene)
  useEffect(() => {
    const action = actions[names[0]]
    action?.reset().play()
    return () => { action?.stop() }
  }, [actions, names])
  return <primitive object={scene} {...props} />
}
useGLTF.preload('https://cdn.3dassets.dev/assets/28629/v1/model.glb')
```

<model-viewer src="https://cdn.3dassets.dev/assets/28629/v1/model.glb" alt="Coaster Lift Hill Section (Theme Park Rides and Coasters)" camera-controls auto-rotate autoplay></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/28629/v1/model.glb
# Metres and +Y up are converted to Blender's Z-up scene automatically.
# Clips arrive as actions; play them from the Dope Sheet > Action Editor.
```

## 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)
var player := model.find_child("AnimationPlayer", true, false) as AnimationPlayer
player.play(player.get_animation_list()[0])
```

## 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/28629/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first.
```
