I do not want a refund. The plugin works well when applied to my player character (keeps him from jerking around). I think I will use this on my player and try to create a client prediction system for the physics actors in my game.
I apologize for the misunderstandings. I am quite new to replication. A quick note, you mention how you made it clear that physics can’t be enabled on both system, but I never had physics enabled on the client, only the server. And for some reason, the player has trouble pushing around a cube when the smooth sync is applied to him.
