Creating monoscopic display in Unity VR

Hello all -

I’m a researcher looking to create a monoscopic display in VR (same image to each eye). I am using the SteamVR plug-in and have two cameras, one to each eye.

The cameras are set to the exact same position and they preview the same image, but in the headset itself they still show two separate images.

Am I missing something? Is there a way to get the same image to each eye?

I created a project a while back (now on GitHub) for a similar situation:

It uses separate rendertextures for each individual eye. Maybe it will be helpful…?

Will take a look. Thank you!

You went through a lot of work to do that! I’m surprised there is no easier way… Should be a toggle/check box. Same with changing the FOV (which I’m also trying to do) - just seems oddly difficult to adjust with the Vive in Unity.

Those viewing this thread in the future, if you want to change the VR field of view along with mono v. stereo.

I’ve adjusted the VR field of view using the Unity Post Processing asset and adding a vignette effect. This restricts the FOV of the camera and blackens the surrounding area to create the restricted tunnel vision effect.
