# MDLSkyCubeTexture

A generator of texel data that creates cube textures using a physically realistic simulation of the sunlit sky.

## Declaration

```swift
class MDLSkyCubeTexture
```

## Overview

Overview The sky textures generated by this class can can be useful as environment maps or light probes in rendering. Like other procedural MDLTexture subclasses, the MDLSkyCubeTexture class generates texel data only when that data is first referenced, and then caches it for future use.
