## About

A regional diesel multiple unit driving car: a 23 m lofted body with a raked cab end and a wrap-around windscreen, single leaf plug doors with grab poles and step boards, a full width warning panel and an obstacle deflector. Underfloor diesel raft with an engine block, side-mounted radiator matrix, fuel tank and silencer, a roof exhaust stack with a radiator grille, and one powered and one trailing bogie. Wheel flanges rest on y=0 so the rail plane sits at y=0.03; place the vehicle at y=0.57 over a track module to stand it on the railhead. Automatic coupler ports sit at each end at y=1.07. Bounding size 3.00 x 4.80 x 23.11 m (X x Y x Z). Metre units, +Y up, +Z forward, resting at y=0. Named pivot nodes: door-r1-a, door-r1-b, door-r2-a, door-r2-b, door-l1-a, door-l1-b, door-l2-a, door-l2-b, bogie-front-axle-1-right, bogie-front-axle-1-left and 6 more. Rigid node-transform clips: open, close and wheel-roll. No skinning. No collision or navigation data.

## 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/13668/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 RegionalDieselMultipleUnitDrivingCarModernRailAndMetroNetwork(props) {
  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/13668/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/13668/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/13668/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/13668/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first.
```
