Showing another camera in VR Preview?

Hi all,

I am using unreal engine to run VR+eye-tracking research. So far I am able to stream the eye-tracker data from the Oculus Pro eye-tracker (through LabStreamingLayer) and has an invisible ray cast reporting what objects are hit (what I am gazing). But I am having an issue recording the video as currently the preview renders only left or right eyes so the user’s FOV will be different from what is showed in the preview. So my question is

  1. Is there a way to have the VR preview showing both eyes the same time?

  2. Or alternativeky can I attach a new camera to VR_Pawn that will follows the player and show up in preview (instead of showing the VR rendering)?

  3. And also does UE5 has a build in function that I can use to record videos?

  4. If setting up a third camera, is it possible to make the ray cast only visible by the third camera not by the player (VR camera)?

Thanks all.
