AActor::SetMinNetUpdateFrequency

function Engine Blueprint Since unknown

#include "GameFramework/Actor.h"

Access: public Specifiers: UFUNCTION

Description

Sets the rate the engine throttles down to when this actor's replicated properties have not changed recently. Acts as a floor to prevent the actor from being skipped entirely during quiet periods.

Caveats & Gotchas

• Setting this equal to NetUpdateFrequency disables throttling entirely, which may waste bandwidth on actors that are frequently idle.
• A value of 0 effectively allows the engine to skip the actor indefinitely when nothing changes — use with caution on actors that need periodic keep-alive updates.
• Direct access to the underlying MinNetUpdateFrequency property was deprecated in UE 5.5; always use this setter for forward compatibility.
