AActor::SetCallPreReplicationForReplay

function Engine Since 4.20

#include "GameFramework/Actor.h"

Access: public

Description

Controls whether `PreReplicationForReplay()` is called before each replay replication pass. Use to opt out of per-frame replay replication overhead for actors whose state does not change.

Caveats & Gotchas

• This only affects replay recording, not live gameplay replication. `SetCallPreReplication` and `SetCallPreReplicationForReplay` are independent flags.
• Disabling this while using demo recording may cause divergence between what the replay records and actual gameplay state if the actor does mutate replicated properties during play.
