# firstMaterial

The first material attached to the geometry.

## Declaration

```swift
var firstMaterial: SCNMaterial? { get set }
```

## Discussion

Discussion Calling this convenience method is equivalent to retrieving the first object from the geometry’s materials array. This property’s value is nil if the geometry has no attached materials.
