LargeWorld System (Advanced)

The LargeWorld System is a custom optimization framework specifically designed for massive landscapes and open-world environments. Unlike traditional distance culling methods, this system uses a more dynamic approach to balance visual fidelity and rendering performance.

How It Works

• Near Distance High-quality Nanite meshes are rendered close to the camera at their highest resolution, delivering rich visual detail where it matters most.

• Far Distance The original meshes are replaced with larger, high-quality Nanite versions, typically scaled up 4× in size. This approach keeps the landscape visually filled without drawing as many small instances, significantly reducing overdraw and improving GPU performance.

• Material-Driven Swapping Mesh transitions are handled manually through the material system, based on distance from the camera. This allows for full control over when and how the transitions occur.

⚠️ When to Use

The LargeWorld System is intended only for large-scale environments, such as open-world games or expansive outdoor scenes.

Using this system in small or enclosed levels may result in unnecessary overhead and reduced performance. For indoor or smaller environments, standard Nanite meshes without this system are recommended.
