How can I blur just one camera in VR having two on the display

Hello everybody. First of all, I just wanted to say that I’m new in the unity world, so I wanted to say sorry if I don’t understand some things that you guys do.

My problem is that I want to display two different cameras on a single display, one in the center on top of the second one, and other one surrounding the first one (under it) whit a higher FOV. What I want to do is to blur de second one, but the blur doesn’t work. I’ve tried many things and nothing worked.

I would be so grateful if you could help me.

You added VR. I do not think this is easily doable in VR.

If you don’t use VR (please don’t use the VR tag), tell what you already tried.

Blurring a screen is hard, but possible. Maybe use a custom render feature or full screen shader graph with box blur
