It is not possible to do this with the Native VR integration in Unity. It is also not something we have planned to be added.

Many thanks for the answer what would be the best way to work around this?

Does -multidisplay and Display Activate helps in any way?

Thanks a lot

You might be able to use NativeTexturePtrs (Unity - Scripting API: Texture.GetNativeTexturePtr) in order to retrieve pixel data off one buffer and then overwrite the Texture of the Camera rendering to the game view. Other than that, no, using multidisplay or Display Active will not render both Eyes to the game view. We did not intend to have both eyes drawn to the game view and thus we haven’t scheduled work to implement this feature.

Hi again :slight_smile: I’m not an expert to unity yet so please be patient with my questions :slight_smile:

  1. Would Unity Pro help in any way?

  2. How I think it could work for future and I believe it would be useful for others as well is:
    Cam 1: Target Eye “Left”, Target Display 1 → Primary Display
    Cam 2: Target eye “Right”, Target Display 2 → Secondary Display
    Would it be difficult for you to schedule this to your roadmap?

  3. For the moment I can live with both outcomes, whatever is easier to implement:

  • To have both eyes on one screen split vertically
  • To have left eye displayed on primary display and right on seconday secondary

And back to your suggestion:
Currently I have

Cam L → Target Eye: Left eye; Culling Mask: Left
|
-----(Child of CamLL) Cam L → Target Eye: Left Culling Mask: Left; Target Texture: RenderTexture1

Cam R → Target Eye: Right; Culling Mask: Right
|
-----(Child of CamRR) Cam R → Target Eye: Right; Culling Mask: Right; Target Texture: RenderTexture2

And I render texture to the cubes on the screen. It works fine, so well I have a texture ready to be combined with each other.

Can you now please point out how can I access a display and render combined textures?

Many thanks
