Upgrading to AR Subsystems version 4.2

To upgrade to AR Subsystems package version 4.2, you need to do the following:

• Use new methods to query for occlusion subsystem support.
• Use Unity 2020.3 or newer.

Use new methods to query for occlusion subsystem support

The XROcclusionSubsystemDescriptor provides a means to query for the capabilities of an XROcclusionSubsystem. Previously, these capabilities were booleans, but some platforms may take a few frames to determine a capability. Those bool properties have been deprecated in favor of properties that return a Supported state, which includes a Supported.Unknown state to indicate support for the feature or capability is not yet known. These properties are:

• humanSegmentationStencilImageSupported
• humanSegmentationDepthImageSupported
• environmentDepthImageSupported
• environmentDepthConfidenceImageSupported

Use Unity 2020.3 or newer

This version of the package requires Unity 2020.3 or newer.
