Question Combining Cameras in URP

For my project I want to render 3 cameras (using the URP forward renderer) and combine them into a single panoramic texture. (and maybe apply some effects onto that combined view)

I want each of the cameras to use the URP forward renderer individually.

In the legacy render pipeline I could just use a Graphics.Blit() to combine the views but it looks like URP can't do that easily out-of-the-box. Is the right approach to create a new full-screen-quad renderer and assign it to a new camera?

Is there a way to just do this via SRP calls instead of having another camera in the scene?

 

Have you tried camera stacking (note that Camera stacking is currently super buggy for VR and I've filed several bug reports).

 

No, I don't want to stack them. I want to use multiple cameras to make a RenderTexture with a super wide field of view.

 

A straightforward solution might be to have 3 base cameras rendering onto 3 individual render textures and a fourth camera rendering a UI canvas with 3 raw images set up next to each other. Assign the render textures to the UI raw images and you should be good to go

 

Thanks, that's definitely an interesting approach.

But I'm looking for a way to do it without that extra camera.
