Attaching a rigidbody to the ARCamera prefab is causing problems... I have a few Game Objects set as children of the ARCamera. But as soon as I add a rigidbody to any of the children GameObjects or to the ARCamera, the children disappear when I run the app on my iPhone. Running the game in Unity however seems to work just fine.
Are there any known issues with attaching rigidbody to the ARCamera or its children?
