Creating and Using Prefabs
A Prefab is composed of a collection of Objects that can be instantiated several times. Each of these Instances acts like a single Object and can retain unique properties via overrides. The characteristics that are shared through all Instances of a Prefab are managed from the Prefab Asset which is generated whenever a Prefab is created. Changes made in the Prefab Asset are enacted across all Instances.
This section shows how to get started with Prefabs. It first describes how Prefabs can be created and next it shows how to edit the Prefab Asset, thus modifying all Instances of the Prefab. Finally, it describes how to edit one single Prefab Instance.
Creating Prefabs
To create a Prefab, go to the Scene Outliner and select the Objects that will compose the Prefab, then right-click and click on Make Prefab. This will create a Prefab consisting of the selected Objects and a new Prefab Asset will be generated in the Asset Manager.
New instances of the Prefab can be created by either duplicating the existing Prefab in the Scene Outliner or by dragging the Prefab Asset from the Asset Manager to the Scene Outliner or the Scene.
Editing the Prefab Asset
To edit the Prefab Asset, double-click the Prefab in the Asset Manager. This will open the Prefab View in both the Scene Outliner and Attribute Editor. The Prefab View is indicated by a purple circle. Changes made here affect all instances of the Prefab.
For the changes made in the Prefab Asset to take effect, it is necessary to save them by pressing the Save prefab button on the top right corner of the Viewport.
Editing a Prefab Instance
Each Instance of a Prefab can be modified on its own and this overrides the Attributes from the Prefab Asset. To do this, simply edit the Object in the Prefab instance.
