## About

Free 3D model of a straight overhead carrier rail section on floor posts, a 6 m modular monorail for a car factory assembly line game asset kit. Dimensions 1.93 by 4.62 by 6.00 m (X by Y by Z). Metre units, +Y up, +Z front, origin on the footprint at ground level. Connectors: in (rail) at (0.00, 4.40, -3.00) facing (0, 0, -1); out (rail) at (0.00, 4.40, 3.00) facing (0, 0, 1). A 6.00 m blue box rail at 4.40 m carried on two white steel floor posts at 4.40 m, with a yellow power track down one side. In and out rail ports on the line axis butt sections into a run and meet the curve. Drop the overhead carrier hanger under it. Static geometry: the rail, the posts and the power track do not move. Car plant palette: light grey epoxy floor, safety yellow, white plant steel, charcoal, safety orange, equipment blue, two gloss body colours, matt primer, skin, glass and emissive amber. Standard PBR materials with embedded procedural maps. 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/27821/v1/model.glb', (gltf) => {
  scene.add(gltf.scene)
})
```

## React Three Fiber

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

export function OverheadRailStraightCarFactoryProductionLine(props) {
  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/27821/v1/model.glb')
  return <primitive object={scene} {...props} />
}
useGLTF.preload('https://cdn.3dassets.dev/assets/27821/v1/model.glb')
```

## 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/27821/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/27821/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
```
