How to read headset position but do not render to the headset screen?

Questions & Answers
1

I want to do a scene in VR where there are 2 cameras: the third person camera and the headset camera.

The headset camera is used to move the head around in the scene with a Vive headset. And the third person camera is used to observe what’s happening. I will record the third person camera as a video file for show on YouTube. I don’t want to render the headset view because it’s making the frame rate drops.

How do I stop the headset view from being rendered or at least increase the frame rate while it’s being rendered?

The solution is to set culling mask field on the Camera component to Nothing on the headset camera and set Target eye only to the left or right eye, instead of both eyes.

This will reduce the computation time of the headset camera significantly.
