struct ClothCollisionGroupSet
```

## Topics

### Creating a group set

[`init(groups: [Int])`](/documentation/RealityKit/ClothCollisionGroupSet/init(groups:))

Creates a collision group set from an array of numbered groups.

### Accessing default groups

[`static let defaultBodies: ClothCollisionGroupSet`](/documentation/RealityKit/ClothCollisionGroupSet/defaultBodies)

Default option reserved for cloth bodies.

[`static let defaultColliders: ClothCollisionGroupSet`](/documentation/RealityKit/ClothCollisionGroupSet/defaultColliders)

Default option reserved for colliders.

### Initializers

[`init(rawValue: UInt32)`](/documentation/RealityKit/ClothCollisionGroupSet/init(rawValue:))

Creates a collision group set from a raw bitmask value.

### Instance Properties

[`var rawValue: UInt32`](/documentation/RealityKit/ClothCollisionGroupSet/rawValue)

The raw bitmask value of the set, where each set bit represents a group between 1 and 32.

### Type Properties

[`static let all: ClothCollisionGroupSet`](/documentation/RealityKit/ClothCollisionGroupSet/all)

Option that includes all groups.
