StreetscapeDemo's Camera AR Ball Shooter is set up, but there is no reference to it.

It looks like ARCamera originally had Camera AR Ball Shooter, but it was now Missing.

I found this error while I was looking into this sample that didn't show any geometry, I removed the AR Ball Shooter related code and it showed the mesh that I couldn't see for a long time.

NullReferenceException: Object reference not set to an instance of an object.
