By default, the loaded node is not synchronized, which is suitable for static objects at run time and at the same time saves performance. For dynamic objects to be synchronized, the suitable synchronization mask should be set.Arguments

This is a network analogue of the loadNode() method of the World class. By default, the loaded node is not synchronized, which is suitable for static objects at run time and at the same time saves performance. For dynamic objects to be synchronized, the suitable synchronization mask should be set.Arguments
