I want to render different things using different cameras to different monitors. Main Camera is Stereo Camera to ZSpace display(VR views). other cameras is

The Unity Setting likes this:

  1. Camera that is you VR camera (eyes): Target Display = Display 1 > Target Eye = BOTH

  2. Second camera (for desktop monitor): Target Display = Display 2 > Target Eye = None (Main Display)

It works well in normal computer (no vr effects), like this：(right is main camera)

But it works wrong when run in ZSpace. Maincamera is ok(the right one), other cameras show nothing(left one):

How to solve this problem, or can i use other ways to have this effect? VERY urgent ！

As far as I know, rendering a secondary monitor in addition to a stereo display is something that Unity3D can’t do yet.

Depending on what you’re intending to draw on the secondary screen, an alternative option may be to run a second app on the same system that networks to the first app.
