## About

Lower half of a 10 m vertical loop: steel coaster track sweeping from level up through 180 degrees to the inverted crown, where it meets the upper half. Free 3D model for theme park, roller coaster and tycoon game scenes in Unity, Godot, Unreal, three.js and Blender. Overall 1.06 by 10.88 by 6.48 m (X by Y by Z). Metre units, +Y up, +Z forward. Pivot on the grid origin at the level entry. The loop advances 4 m along +Z over the full revolution, so the two halves close into a loop whose exit clears its entry by 4 m. Static geometry; no rig, 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/28631/v1/model.glb', (gltf) => {
  scene.add(gltf.scene)
})
```

## React Three Fiber

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

export function CoasterVerticalLoopLowerHalfThemeParkRidesAndCoasters(props) {
  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/28631/v1/model.glb')
  return <primitive object={scene} {...props} />
}
useGLTF.preload('https://cdn.3dassets.dev/assets/28631/v1/model.glb')
```

<model-viewer src="https://cdn.3dassets.dev/assets/28631/v1/model.glb" alt="Coaster Vertical Loop Lower Half (Theme Park Rides and Coasters)" 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/28631/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/28631/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
```
