AActor::RegisterAsFocalPointInPhysicsReplicationLOD

function Engine Blueprint Since 5.3

#include "GameFramework/Actor.h"

Access: public Specifiers: UFUNCTIONBlueprintCallable

Description

Registers this actor's root component physics object as a focal point in the Physics Replication LOD system, causing the engine to allocate higher-fidelity physics replication budget around this actor.

Caveats & Gotchas

• Only relevant when the Physics Replication LOD system is active (requires the Physics Prediction plugin and specific project settings). Without it this call is a no-op.
• Must be called on the server — clients do not own the physics replication authority needed to influence LOD budget allocation.
• Balance the number of focal points carefully; too many defeats the LOD optimization and can increase server bandwidth.
