Enumeration Case

ARWorldTrackingConfiguration.EnvironmentTexturing.manual

ARKit generates environment textures only for probe anchors you explicitly add to the session.

Declaration

case manual = 1

Discussion

When you use this environmentTexturing option, you must manually choose when and where to generate environment map textures:

  1. Create an AREnvironmentProbeAnchor object with a transform indicating its position in the scene.

  2. Add the probe anchor to the session with the add(anchor:) method.

If you display AR content using ARSCNView, SceneKit automatically retrieves texture maps from probe anchors and uses them to light the scene. Otherwise, use a delegate method such as session(_:didUpdate:) to find out when the probe anchor's texture has been updated and access the environmentTexture property.
