## Fields

- [`IFR`](/api/Sandbox.PhysicsBodyBuilder.SimplifyMethod/IFR): Iterative Face Removal - removes faces to reduce complexity.
- [`IVR`](/api/Sandbox.PhysicsBodyBuilder.SimplifyMethod/IVR): Iterative Vertex Removal - removes vertices gradually.
- [`None`](/api/Sandbox.PhysicsBodyBuilder.SimplifyMethod/None): No simplification - use the exact points provided.
- [`QEM`](/api/Sandbox.PhysicsBodyBuilder.SimplifyMethod/QEM): Quadratic Error Metric - prioritizes preserving shape accuracy.
