I'm wondering if anyone can suggest a workaround for the broken ARKit body tracking in iOS / iPadOS 18.0 and 18.1?
The orientation for foot bones (and possibly other bones) is incorrect in the ARBodyAnchor returned via ARView.session.delegate update method. It works correctly in iOS / iPadOS 17.x.
The same failure occurs in a SceneKit app via a ARBodyAnchor in ARSCNViewDelegate.
You can easily verify the problem using Apple’s own sample app: https://developer.apple.com/documentation/arkit/arkit_in_ios/content_anchors/capturing_body_motion_in_3d
Any help would be greatly appreciated.
