  Type Name Description
Public function void

SetPhysicsReplication ( IPhysicsReplication* InPhysicsReplication
)

 If possible, avoid directly setting physics replication at runtime - this function will take ownership of the IPhysicsReplication's lifetime. Instead, specify a PhysicsReplication factory and if you must change the replication class at runtime run RecreatePhysicsReplication after having set the factory.
