Hi,
When the rendertarget actor is rotated inside the widget, it rotates in the world as the actor as well.
it seems to me that you want to have this whole logic per client, independent from all other clients. If that is correct, then you should not replicate any of the logic.
If rotating the rendertarget actor on one client, replicates to another client, then I guess that means you have replication in there somewhere that you would need to remove (since it seems to me you don’t want this to replicate / sync between clients).
And by the way, widgets never replicate, they only exist locally. So you can’t have any RPCs or replicated variables in them, they won’t do anything.
