I don’t know what is happening but when the Server throws a projectile, the Client sees it. But when the Client is the author of the projectile, it’s invisible to Server. The projectile have nothing of special and it’s replicated. Please, help me guys!
Look up the chain events and run the projectile spawning at least from the server, and then to the client. If it’s not a complex chain the multicast feature on a custom event might do it.
I think you need to spawn on the server for the actors to get replicated. How do I spawn an actor from a client? - UE4 AnswerHub
