What's new in version 4.2

Summary of changes in AR Foundation package version 4.2.

The main updates in this release include:

Added

• Add support for temporal smoothing of the environment depth image. This allows you to request that the environment depth image be smoothed over time. Not all providers support this feature. You can query for support with XROcclusionSubsystemDescriptor.environmentDepthTemporalSmoothingSupported.
• Added options to the ARPlaneMeshVisualizer component to control when MeshRenderer and LineRenderer components should be enabled. See
  • ARPlaneMeshVisualizer.trackingStateVisibilityThreshold
  • ARPlaneMeshVisualizer.hideSubsumed

Updated

• Add description for occlusion on the main AR Foundation manual page, and edit the human segmentations description.
• The ARSession optionally sets the application's vSyncCount and targetFrameRate (see matchFrameRateRequested). In earlier versions, the original values were not restored when the ARSession was disabled. The behavior has changed so that the original values are restored when the ARSession was disabled if the frame rate was set while the ARSession was enabled.
• Update XR Plug-in Management dependency to 4.0.

Fixed

• Added missing icon to the AROcclusionManager.
• Replace uses of PostProcessScene attribute with IProcessSceneWithReport callback mechanism. This prevents scene hashes from changing when adding the AR Foundation package.
