Hello i got that issue when testing multiplayer steam with friends.
Host works perfectly , but client not .
On editor when i play 2 devices i dont have problem like that .
You probably have the camera arm component or the camera component set to replicate. If so only set replicate on the main actor.
You are getting miss matches of component positions between server and client and its trying to correct the changes to the server location.
It’s only visible online because of lag.
If you turn on lag emulation in the editor it will also look bad.
If you are not worried with cheating then you can try turning on client side authoritative position.
But turning off component replication is probably the better option.
cant find the camera component - replicated or so , where can i find it?
It should be in the character actor. Check the spring arm component (if its there) and the camera component.
The replication settings are in their details panel
i didnt have any replication set into camera , but i checked also capsule component , there component replication was checked , now on editior with delay i have working it good , now i have to check this with my friends . greets man
