The lastest documentation for Plane Detection can be found in the documentation 

When using plane detection there are two modes available default and Scene Understanding (spatial meshing-based plane detection).


  • The option is available under Project Settings > XR Plug-in Management > OpenXR > Plane Detection.

Known issues with Scene Understanding

  • When using ARRaycast to test for a hit against an ARPlane generated by Scene Understanding the ray will be cast against the spatial mesh instead. The id of the ARRaycastHit result is the id of the mesh, not of the ARTrackable plane. 
  • Setting the detection mode in the AR Plane Manager is not possible at this moment. Every plane orientation will be tracked regardless of the chosen option. 


  • The option to use scene understanding can be toggled at Project Settings > Plugins > Snapdragon Spaces > Extensions in the Features tab.

Known issues with Scene Understanding

  • Filtering for horizontal or vertical planes only is not possible when using Scene Understanding.
