Mirroring options

Hello,

I am developing a game for Windows with DirectX and OculusVR support.
Now, I want to display the content of the HMD on my desktop monitor.
Therefore I create a MirrorTexture by ovr_CreateMirrorTextureDX.

Certainly the mirror displays both the left and right eye. But I want it to display only one eye in rectlinear view.

How is that possible?
