Thumper's Midnight UE4 Replication Crash Course
I made this video real quick to help the team, and any other dev seeking replication knowledge. I go over some common replication mistakes, and how you can debug them.
Error in video: At 28:10 I connected a branch's true node instead of the false node. That's backwards. A DEDICATED server shouldn't ever run cosmetic logic that doesn't effect game play. However a listen server (The IsServer node) would want to run cosmetic logic still, because there's a player on that machine and they'd want to see the effects.
