Default settings should work. I’ll check some things out tonight to make sure it’s all still working as expected with dedicated server.
One thing may be that you still have Replicate Movement checked. You’ll want to uncheck that as Smooth Sync will be handling that behavior and they may be fighting each other to set the position/rotation of the object.
Another thing you may want to check is that your movement code isn’t trying to move the ships on your clients because Smooth Sync should also be the only one handling that (if the server is the owner or there is no owner for the ship that is).
