public static bool IsDisconnectedFromPrefabAsset(Object componentOrGameObject);


componentOrGameObjectThe object to check. Must be a GameObject or component.


bool True if the instance is disconnected.


Returns true if the given object is part of an instance where the PrefabInstance object is missing but the given object has a valid corresponding object.

The disconnected Prefab workflows have been removed from Unity because of ambiguity when it comes to nesting and variants. However, disconnected Prefab instances are still common when upgrading Prefabs from projects originating from versions of Unity prior to the introduction of improved Prefab workflows.

If you have disconnected Prefabs you should consider unpacking them completely or turnning them back into connected Prefab instances by reverting the instances.
