So I tried this solution but it did not work Set Actor Enable Collision not replicated. So when I am a client I execute event on server and multicast disable collision both on server and client. And for the server side I check If i have authority and I also multicast the disable collision. I am actually using Lyra. The problem is when you are a player who is the server you can walk through the player who is the client. But when you are a player who is the client you can’t properly walk through the player who is the server.
