Main Camera became ar camera automatically in Unity 2017,mainCamera becomes AR Camera automatically

For Unity 2017.if I checked "Vuforia augmented reality support", my Main camera in scene would be added vuforiaConfig automatically and became an AR camera ,how to avoid it ?

 

Hello @wwcc123

This is a known behaviour that is being addressed in an upcoming release. The current work around for this is to place the ARCamera in your scene instead of MainCamera and disable the VuforiaBehaviour component on it.

Apologies for the inconvenience.
