BP_VisionSync is a plug-and-play Actor Component that dramatically improves runtime performance by hiding actors outside the player's vision range and revealing them only when they enter a defined box area — completely eliminating unnecessary draw calls, shadow calculations, and Lumen/Nanite overhead for out-of-range objects.

How It Works

A Box Collision is dynamically spawned at runtime and attached to the owner. Any actor tagged with a customizable tag (default: "Optimize") is hidden at game start and automatically shown or hidden as it enters or exits the collision box — no Tick, no manual setup, no performance cost at idle.

Key Features

- Drop-and-go Integrated in FirstPerson Character

- Fully dynamic: Box Collision is created at runtime, no manual component attachment needed

- Customizable box extent and culling tag per instance via exposed variables

- Event-driven architecture (no Tick) for maximum efficiency

- Compatible with UE5 Nanite, Lumen, and existing culling systems

- Works on all platforms including mobile

Performance Impact

In scenes with hundreds of actors, this system can reduce up to GPU draw calls by up to 90% depending on scene layout, making it especially powerful for open-world games, indoor/room-based levels, and mobile projects.
