# wantsHDREnvironmentTextures

A flag that instructs ARKit to create environment textures in HDR format.

```
var wantsHDREnvironmentTextures: Bool { get set }
```

## Discussion

The default value is <doc://com.apple.documentation/documentation/Swift/true>. If your renderer supports HDR environment textures, this feature effects more realistic reflections.

RealityKit and SceneKit both support HDR environment textures. For more information, see [Adding realistic reflections to an AR experience](/documentation/ARKit/adding-realistic-reflections-to-an-ar-experience).
