SceneTreeMultiplayerPoll Property

If true (default value), enables automatic polling of the MultiplayerAPI for this SceneTree during idle_frame.

If false, you need to manually call Poll to process network packets and deliver RPCs/RSETs. This allows running RPCs/RSETs in a different loop (e.g. physics, thread, specific time step) and for manual Mutex protection when accessing the MultiplayerAPI from threads.
