# materialNames

The names of the collider materials used by this collider.

```
var materialNames: [String]
```

## Discussion

The default material is used if no matching material name is present in [`ClothSimulationComponent`](/documentation/RealityKit/ClothSimulationComponent).

The material of the collider determines various physical properties of the collider, such as friction.

Note, only the first material name is used.
