# wantsHDREnvironmentTextures A flag that instructs the framework to create environment textures in HDR format. ``` var wantsHDREnvironmentTextures: Bool { get set } ``` ## Discussion If you set [`environmentTexturing`](/documentation/ARKit/ARWorldTrackingConfiguration/environmentTexturing-swift.property) to `.automatic` in iOS 12 or later, ARKit gives you environment textures you cast on your app’s virtual content to create realistic reflections. By default, the framework sets [`wantsHDREnvironmentTextures`](/documentation/ARKit/ARWorldTrackingConfiguration/wantsHDREnvironmentTextures) to . When your renderer supports HDR environment textures in iOS 13, it enables your lighting engine to output more colors, with a more realistic result.  Both and [`ARSCNView`](/documentation/ARKit/ARSCNView) support HDR environment textures. For more information, see [Adding realistic reflections to an AR experience](/documentation/ARKit/adding-realistic-reflections-to-an-ar-experience). For a Metal app that doesn’t yet support HDR environment textures, you can use the following code to receive LDR environment textures until you’re ready to update your renderer for HDR. ```swift if #available(iOS 13, *) { configuration.wantsHDREnvironmentTextures = false } ``` --- Copyright © 2026 Apple Inc.
