# Bone Attachment
Attach meshes to bones of a skinned mesh, such as attaching a sword to a character's hand.
## Technique
Create a `BoneChild` component that uses `useEffect` to add a container group to a bone and remove it on cleanup. The bone reference is obtained from the GLTF nodes after loading the model.
## Key Concepts
- Access bones from GLTF nodes (e.g., `nodes.HandR`)
- Use `bone.add(container)` to parent objects to bones
- Clean up with `bone.remove(container)` in useEffect cleanup
- Apply position/rotation/scale offsets to adjust attachment placement
## Usage
```tsx
const { nodes } = useGLTF('/character.glb')
<BoneChild bone={nodes.HandR} position={[0, 0.3, 2]} rotation={[0, 0, 0]}>
<mesh>
<boxGeometry />
<meshBasicMaterial color="red" />
</mesh>
</BoneChild>
```
