const result = mesh.setParent(parent);
```

## Parameters
| Name | Type | Required | Description |
| --- | --- | --- | --- |
| `parent` | `Mesh \| null` | Yes | Parent mesh/transform reference; use null to detach. |

## Returns
`this` - The same object instance, returned for fluent chaining.

## Type Details
```ts
// No additional descriptor expansion is required for this signature.
```

## Example
```js
const canvas = document.querySelector("canvas");
const wgpu = await WasmGPU.create(canvas);

const geometry = wgpu.geometry.box(1, 1, 1);
const material = wgpu.material.unlit({ color: [0.9, 0.6, 0.2], opacity: 1.0 });
const mesh = wgpu.createMesh(geometry, material);
const parent = null;
const result = mesh.setParent(parent);
console.log(result);
```
