Now that I’m fully engaged in this topic I can pile on more feedback about disabling replication.
Consider the following scenario.
Each player (4) can only see 1 other player in their current frustum. If you disable replication on any of them you disable it for all.
Disabling replication would also eliminate footstep sounds for hidden players. Footsteps are generated using animation notifies. Notifies require animation. With replication off, there’s no updates to the pawn, thus no animation.
You wouldn’t hear them running away or moving around to another position. Then pop, they are back.
In essence the player in the bottom could literally run directly up to the top player and he wouldn’t know it until he’s shot in the back.
