To enable positional head tracking, the following objects are required in the scene:

  • AR Session
  • AR Session Origin

Disable the AR Camera Manager component in the AR Camera GameObject if it is not needed to retrieve RGB camera frames for instance, to avoid camera lifecycle related issues mentioned in the known issues section.

IMPORTANT

From Snapdragon Spaces SDK version 0.20.0, disable the AR Camera Background component in the AR Camera GameObject, as Snapdragon Spaces does not support it. All instances of the component will be automatically disabled at the start of the camera lifecycle to avoid rendering issues mentioned in the known issues section.
