# PrefabStage

> The PrefabStage class represents an editing context for Prefab Assets.

## Definition

* **Type:** Class
* **Namespace:** [UnityEditor.SceneManagement](/engine/6000.5/script-reference/unityeditor/scenemanagement.md)
* **Assembly:** UnityEditor.CoreModule
* **Inherits from:** [PreviewSceneStage](/engine/6000.5/script-reference/unityeditor/scenemanagement/previewscenestage.md)

```csharp
public sealed class PrefabStage : PreviewSceneStage
```

## Remarks

A stage is an editing context which includes a collection of Scenes. The main stage contains all the currently open regular Scenes, while a Prefab stage contains a preview Scene used solely for editing the Prefab in.

The breadcrumbs which are shown in the Scene view when in Prefab Mode each represent a stage. Those with a Prefab icon represent Prefab stages.
