## About

A generic period stage transporter: a bonneted three-axle tractor unit with an exhaust stack, side tank and fifth wheel, coupled to a girder semi trailer on two dual axles with landing legs, outrigger jacks and a lattice erector beam on cradle rings. Bounding size 4.78 x 3.42 x 18.48 m (X x Y x Z). Metre units, +Y up, +Z forward, lowest geometry resting on y=0. Movable parts are separate named nodes with local pivots: wheel-steer-right, wheel-drive-1-outer-right, wheel-drive-1-inner-right, wheel-drive-2-outer-right, wheel-drive-2-inner-right, wheel-steer-left, wheel-drive-1-outer-left, wheel-drive-1-inner-left, wheel-drive-2-outer-left, wheel-drive-2-inner-left, wheel-trailer-1-outer-right, wheel-trailer-1-inner-right, wheel-trailer-2-outer-right, wheel-trailer-2-inner-right, wheel-trailer-1-outer-left, wheel-trailer-1-inner-left, wheel-trailer-2-outer-left, wheel-trailer-2-inner-left, erector-beam. Four padded cradle rings and twin lifting rams sit on the beam. The erector beam is a named node hinged at the trailer rear; every wheel is a named node with an axle pivot. Generic period hardware with no real designations, insignia or markings. 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/15681/v1/model.glb', (gltf) => {
  scene.add(gltf.scene)
})
```

## React Three Fiber

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

export function TransporterErectorWithTractorUnitColdWarMissileSiloAndCommandBunker(props) {
  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/15681/v1/model.glb')
  return <primitive object={scene} {...props} />
}
useGLTF.preload('https://cdn.3dassets.dev/assets/15681/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/15681/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/15681/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
```
