Different cameras not viewing set canvas

I made 2 different cameras, and 2 different canvases, and when I set them both to “screen space camera” and drag the camera into the slot, it disappears. Can someone please help me?

You have to change the Clear Flags (and Depth) of your one of your cameras.

Camera 1 :

  • Clear Flags : Skybox / Solid Color
  • Depth : -1

Camera 2 :

  • Clear Flags : Depth only
  • Depth : 0
