### Remarks

All normal Scenes start with this culling mask by default. The Scenes created through [EditorSceneManager.NewPreviewScene](/engine/6000.3/script-reference/unityeditor/scenemanagement/editorscenemanager/newpreviewscene.md) get their own unique Scene culling mask which is why the GameObjects in those Scenes do not show up in the Scene view and Game view by default.
