### Remarks

When the Editor starts or when packages are installed or removed, the [SubsystemManager](/engine/6000.5/script-reference/unityengine/subsystemmanager.md) searches the packages and loads all XR SDK packages that it finds. Handling this event allows the user to do work they may need after the subsystem manager loads and initializes new subsystem descriptors.

*Note:* This is deprecated, use [SubsystemManager.afterReloadSubsystems](/engine/6000.5/script-reference/unityengine/subsystemmanager/afterreloadsubsystems.md) instead.
