-Only supports dynamically spawned actors, not placed actors -UNetDriver::NotifyActorRenamed now has a PreviousOuter parameter -Net driver notifies any ReplicationDriver (replication graph) of actor renames -ReplicationGraph APIs added to update internal actor level tracking (this can be toggled with the cvar Net.RepGraph.HandleDynamicActorRename) -Added cvar net.CleanUpRenamedDynamicActors that will tell clients to destroy an actor if the server moves it to a level that's not currently visible on the client (disabled by default to preserve current behavior) #jira UE-201875 #rb LouisPhilippe.Seguin [FYI] Todd.Eckert, Jon.Sourbeer [CL 32491240 by ryan gerleve in 5.4 branch]

/**
|
|
* A basic implementation of replication graph. It only supports NetCullDistanceSquared, bAlwaysRelevant, bOnlyRelevantToOwner. These values cannot change per-actor at runtime.
|
|
* This is meant to provide a simple example implementation. More robust implementations will be required for more complex games. ShootGame is another example to check out.
|
|
*
|
|
* To enable this via ini:
|
|
* [/Script/OnlineSubsystemUtils.IpNetDriver]
|
|
* ReplicationDriverClassName="/Script/ReplicationGraph.BasicReplicationGraph"
|
