For example it is street light that i want to toggle using characters. Template = YourTemplateActor; YourActorReference = GetWorld ()-> SpawnActor (SpawnInfo All the ownership does is attach an actor to a player controller to handle replication properly and what gets handled on the server versus the client. If this is done in the CS: In this video I will go through a very basic introduction of Actor Components, this video is intended to make you aware of these features rather than all the I need the primitive component because it applies to anything that has geometry, and that is how I can add force at location to a component that is a static or skeletal mesh. NetUseOwnerRelevancy. There may be another node called "Get Owner" where the target is a Scene Component, which is the one you really want.
