# Scene / Unload

Unload scene from the Opened scenes in Unity Editor. Use 'scene-list-opened' tool to get the list of all opened scenes.

## Inputs

- `name` — required non-empty scene name. Must match an opened scene; otherwise throws.

## Behavior

Runs `SceneManager.UnloadSceneAsync` on the main thread and awaits completion. Returns an `UnloadSceneResult` containing the scene name and an `AssetObjectRef` to its asset (or `null` if the scene was not backed by an asset on disk).

## How to Call

```bash
unity-mcp-cli run-tool scene-unload --input '{
  "name": "string_value"
}'
```

> For complex input (multi-line strings, code), save the JSON to a file and use:
> ```bash
> unity-mcp-cli run-tool scene-unload --input-file args.json
> ```
>
> Or pipe via stdin (recommended):
> ```bash
> unity-mcp-cli run-tool scene-unload --input-file - <<'EOF'
> {"param": "value"}
> EOF
> ```


### Troubleshooting

If `unity-mcp-cli` is not found, either install it globally (`npm install -g unity-mcp-cli`) or use `npx unity-mcp-cli` instead.
Read the /unity-initial-setup skill for detailed installation instructions.

## Input

| Name | Type | Required | Description |
|------|------|----------|-------------|
| `name` | `string` | Yes | Name of the loaded scene. |
