title: How to use PC webcam for AR Foundation in Unity
body: <p>I am currently working on a project that has AR stuff in it, so before I start I've decided to use ARFoundation. Now when my project is done I have to test it, but unfortunately my phone does not support ARKit. So I decided to test it directly in Unity, using its play mode, but when I run it the "Game" panel gets black and I see nothing. I think it is because the webcam is not turning on. So how can I turn on my webcam in Unity in order to test my ARFoundation app?</p>
  
  <p>Thanks.</p>
