In my current project, I am using the Oculus Integration package to interface my app with my Oculus Rift S headset and Unity 2021.3.6f1 URP.
While working on the project I played with the camera settings to get better visuals, and noticed that the field of view attribute always goes back to 90 (even when I set it at run time).
I went over the scripts that were imported from the Oculus package, mainly the following ones (since those are the ones used in the project): OVRCameraRig, OVRManager, OVRHeadsetEmulator.
But wasn't able to find anywhere in the code what is the cause. I even tried searching through all the scripts (using my IDE) for any piece of code that changes the fieldOfView property, and found some scripts but none of them is used in the project, and commenting those lines made no difference…
So, my question is why can't I change my camera's field of view? What caused it to constantly be set to 90?
Its a bad idea to change the default FOV on a VR camera - its meant to match the actual FOV of the headset and most users will experience heavy nausea if you change it more than a few degrees from the correct value. If you want to experience just how bad this feels, place a quad in front of the main camera, with unlit textured material with a texture written to from another camera (with a different fov). This simple solution will not give you stereoscopy, but should be enough to experience just how bad of and idea this is
