# PreviewSceneStage

> The PreviewSceneStage class represents an editing context based on a single preview Scene.

## Definition

* **Type:** Class
* **Namespace:** [UnityEditor.SceneManagement](/engine/6000.3/script-reference/unityeditor/scenemanagement.md)
* **Assembly:** UnityEditor
* **Inherits from:** [Stage](/engine/6000.3/script-reference/unityeditor/scenemanagement/stage.md)

```csharp
public abstract class PreviewSceneStage : Stage
```

## Remarks

You can create a custom type of Stage by implementing a class that inherits from the abstract PreviewSceneStage class. Your custom Stage should ensure any content it controls is moved into the preview Scene that the stage controls.

Your custom Stage class should implement [PreviewSceneStage.OnOpenStage](/engine/6000.3/script-reference/unityeditor/scenemanagement/previewscenestage/onopenstage.md) and [PreviewSceneStage.OnCloseStage](/engine/6000.3/script-reference/unityeditor/scenemanagement/previewscenestage/onclosestage.md). Unity calls those methods when your stage is opened and closed; you should not call them yourself. To open a Stage of your custom type, use [StageUtility.GoToStage](/engine/6000.3/script-reference/unityeditor/scenemanagement/stageutility/gotostage.md).

| ----------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------- |
| [scene](/engine/6000.3/script-reference/unityeditor/scenemanagement/previewscenestage/scene.md)             | The preview [Scene](/engine/6000.3/script-reference/unityeditor/searchservice/scene.md) this stage controls. Stage content should be moved into this Scene. |
| [stageHandle](/engine/6000.3/script-reference/unityeditor/scenemanagement/previewscenestage/stagehandle.md) | See [Stage.stageHandle](/engine/6000.3/script-reference/unityeditor/scenemanagement/stage/stagehandle.md).                                                  |

## Methods

| Method                                                                                                        | Description                                                                                                                                         |
| ------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------- |
| [OnCloseStage](/engine/6000.3/script-reference/unityeditor/scenemanagement/previewscenestage/onclosestage.md) | Unity calls this method when the Stage is closed. Classes that inherit from PreviewSceneStage should implement cleanup logic in this method.        |
| [OnOpenStage](/engine/6000.3/script-reference/unityeditor/scenemanagement/previewscenestage/onopenstage.md)   | Unity calls this method when the Stage is opened. Classes that inherit from PreviewSceneStage should implement initialization logic in this method. |
