## About

A drilling projectile. The lathed penetrator body is wrapped by two swept helical ribbons that make one and a third turns and shrink toward the tip, and a lathed hot flare closes the tail. Bounding size 0.25 by 0.23 by 0.92 m, metres, +Y up, +Z forward. Origin: free. The origin is the centre of the segment on its axis, midway between the two chain ports, so a developer places this mesh by the point the effect emits from rather than by a base. The geometry surrounds it, reaching 0.12 m below and 0.12 m above the origin. Opaque solid geometry throughout: this pack uses no alpha blending and no transmission, so the silhouette and the emissive material carry the read. Static mesh with no animation clip, no skinned rig, no collision and no 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/21878/v1/model.glb', (gltf) => {
  scene.add(gltf.scene)
})
```

## React Three Fiber

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

export function SpiralDrillBoltVFXMeshLibrary(props) {
  const { scene } = useGLTF('https://cdn.3dassets.dev/assets/21878/v1/model.glb')
  return <primitive object={scene} {...props} />
}
useGLTF.preload('https://cdn.3dassets.dev/assets/21878/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/21878/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/21878/v1/model.glb")) await gltf.InstantiateMainSceneAsync(transform);
```
