Description

The PrefabStage class represents an editing context for Prefab Assets.

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.
