void SetRootActor

ADisplayClusterRootActor & NewRootActor
&41;
Remarks
Set the root actor of the DisplayCluster being controlled. This will also update the renderer's root actor. Don't call this if the helper was created with an existing preview renderer, as it will automatically the root actor from that renderer.
