### Remarks

You can use this function for tooling that needs to access GameObjects but where the scene should not be displayed in the Hierarchy. Make sure to call [EditorSceneManager.ClosePreviewScene](/engine/6000.3/script-reference/unityeditor/scenemanagement/editorscenemanager/closepreviewscene.md) to prevent leaking scenes.
