UActorComponent::IsHLODRelevant

function Engine Since 4.0

#include "Components/ActorComponent.h"

Access: public Specifiers: virtualconst

Description

Override to indicate that this component should be included in HLOD (Hierarchical Level of Detail) proxy generation. Returns false by default; static mesh components override this to return true.

Caveats & Gotchas

• Only meaningful at cook/build time and in the HLOD builder tool. At runtime, the HLOD proxy already exists and this virtual is not called on the original component.
• If you have a custom component that renders custom geometry not inherited from UPrimitiveComponent, you must also override `GetHLODProxyComponents` and `ComputeHLODHash` (both editor-only) for correct HLOD proxy generation.
