Unreal Chaos Skill

Chaos physics system for Unreal Engine.

Overview

This skill provides capabilities for implementing physics-based destruction, vehicles, and soft body simulation using Unreal's Chaos physics system.

Capabilities

Destruction

• Create geometry collections
• Configure fracture patterns
• Handle debris simulation
• Manage collision clusters

Vehicle Physics

• Implement wheel vehicles
• Configure suspension
• Handle aerodynamics
• Manage vehicle networking

Cloth Simulation

• Configure cloth assets
• Handle collision
• Manage constraints
• Optimize performance

Physics Fields

• Apply force fields
• Create attraction/repulsion
• Handle noise fields
• Manage field interactions

Prerequisites

• Unreal Engine 5.0+
• Chaos enabled (default)

Usage Patterns

Geometry Collection Setup

1. Create Geometry Collection from mesh
2. Configure fracture settings
3. Add cluster connections
4. Set physics properties
5. Place in level

Vehicle Setup

// 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
