I will answere my question, so it can maybe help someone.
You have to remove the plugin from the engine location to your project.
If you have no Plugins folder in your project folder create one and copy the SmoothSync
plugin in this created plugin folder.
I have another question i am making a little tank game so i use smooth sync to replicate
the movement smoothly, the second phase of the project will be to make the turret turning
with the mouse cursor. When i finish with all calculation i will have some extra transform let’s
say “FVector turretPosition” is it possible to add this FVector to the smoothSync packet who is already replicating the position and rotation from the main base tank object ?
Thanks.
