Disclaimer i’m a novice to cpp. I’m using multiplayer origin rebase with default character movement component, all is working as expected only issue is the server is always correcting the player pawn because it exceeds the LocDiff in the above code as UpdatedComponent->GetComponentLocation() is the location on the server and ClientWorldLocation is the location on the client in accordance with their own “view” of the world origin. Now i tried doing origin rebase for the ClientWorldLocation vector to no success and my question would be is there anyway to rebase the client coordinates onto the server or the client so the correction actually happens when theres an actual location discrepancy instead of always. Thank you
4.27 has the fixed code, clients never sent their rebased location
