Create Geometry Collection from mesh 2. Configure fracture settings 3. Add cluster connections 4. Set physics properties 5. Place in level ``` ### Vehicle Setup ```cpp // Configure in Vehicle Movement Component WheelSetups.Add(FWheelSetup{ WheelClass, BoneName, WheelOffset }); ``` ## Best Practices 1. Profile destruction complexity 2. Use LOD for distant debris 3. Configure sleep thresholds 4. Test networked destruction 5. Manage cluster counts ## References - [Chaos Documentation](https://docs.unrealengine.com/5.0/en-US/physics-in-unreal-engine/)
