I am developing a VR application. I will show the different object to the left and right eyes. I will have a GUI that I will not show in VR HMD. I want to show left and right camera view and my gui on the desktop monitor. is this possible?

More information on your setup would probably get some more/better answers. I’ll take a guess and believe you’re using SteamVR. As such, it is possible yes.
Drawing or not drawing to different cameras is fairly easy by using the camera’s culling mask.
[Unity - Manual: Camera component](https://docs.unity3d.com/Manual/class-Camera.html) ← should find some info there.

Set up a second UI only camera and set its layer to UI in the components dropdown. Have the other cameras not use the UI layer. The next trick after that that I am seeking i how to get the OVR pointer events and have them trigger clicks that are already on the UI buttons and widgets.

I think I couldn’t explain my problem well. I have not a problem with the vision on the oculus rift. when i start my application it opens a window on my desktop. it shows just left or right eye camera vision. i can add a camera to my scene to see a UI just on desktop window. i set this camera’s target eye as “None (Main Display)”. i set this camera viewpoint rect as X:0 and Y:-0.7. so I can get MY CANVAS UI part as i sent in my previous post. When i use camera viewport rect parameters to get LEFT EYE and RIGHT EYE parts it affects the vision on oculus rift. i can add 2 cameras more and make them the child of Oculus LeftEyeAnchor and RightEyeAnchor camera game objects.then i can set viewport rect to get LEFT EYE and RIGHT EYE parts. This will mean double rendering. How can I get left and right eye camera renders of Oculus and show them separately on the window on my desktop?

Ya know… Digging through hundreds of docs yesterday I did come across some render VR thing that passed the string (“Split”). I just woke up and am having coffee so my memory of it is vague but using Split in your searches may help you find the method.

@ippdev afaik split is to generate output for google cardboard devices. i use oculus rift. i googled unity vr split and i found info for cardboards.
When i use target texture feature, i get what i want on application windows. this time HMD is black. As i understand oculus gets left and right camera output directly to the HMD displays. It shows just left eye camera output as full screen. i think only workaround for this, is to use 2 more cameras as child of anchor cameras for ui panel.

at last, i did it;
void OnRenderImage(RenderTexture src, RenderTexture dest)
{
Graphics.Blit(src, dest);
Graphics.Blit(src, TargetRenderTexture);
}
