When you create an instance of a prefab, the Inspector contains specific prefab settings which you can use to edit the prefab instance and its parent prefab asset.
Opens the Overrides dropdown window which displays any overrides of the prefab instance. Use this window to apply overrides from the instance to the prefab asset, or revert overrides on the instance back to the values on the prefab asset. The Overrides window is only available for the root prefab instances, and not nested prefabs.
You can apply all changes to the asset with the following options:
If you want to apply or revert individual changes, select the specific override in the list, and then use the Revert or Apply buttons on the individual override.
For more information on prefab overrides, refer to Override prefab instances.
Selects the parent prefab asset of the prefab instance in the Project window.
Open the parent prefab asset of the prefab instance in prefab editing mode.
