## About

A tube fed pump action shotgun with a ribbed fore-end on twin action bars, a vent rib barrel with a bead sight and a walnut stock. Dimensions 0.076 x 0.186 x 0.920 m (X x Y x Z). Origin at the footprint centre, resting on y = 0; metre units, +Y up, muzzle and point toward +Z. Named pivots: pump at (0.0077, 0.1283, 0.0141). Connectors: optic optic-rail at (0.0077, 0.1894, -0.1089) facing +Y; muzzle muzzle at (0.0077, 0.1485, 0.4602) facing +Z. The trigger linkage, the gas system, the extractor, the feed pawls and any belt run are modelled as solids and left static: a rigid node transform cannot drive a linkage honestly, and faking one costs a consumer more than it gives. Rigid node-transform clips open, close drive named nodes on their own pivots. No skinning and no skeleton. Blued gunmetal, bright machined steel, dark anodised alloy, black and dark earth polymer, rubber, walnut, brass, copper, leather, olive paint, optical glass, concrete and emissive red, green and warm white for reticles, lasers, tritium and lamps. Physically based flat colours with no texture maps. Original invented design: no real make, model, manufacturer or marking is represented. Free 3D model for Unity, Godot, Unreal, three.js and Blender. 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/32964/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 PumpShotgunMegaWeaponPack(props) {
  const { scene, animations } = useGLTF('https://cdn.3dassets.dev/assets/32964/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/32964/v1/model.glb')
```

<model-viewer src="https://cdn.3dassets.dev/assets/32964/v1/model.glb" alt="Pump Shotgun (Mega Weapon Pack)" 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/32964/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/32964/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
// Clips import as legacy AnimationClips on the root; GetComponent<Animation>().Play() starts the first.
```
