If you don't mind me asking what did you use for your vignette? I tried to use vr tunneling pro and it worked in the unity editor but once I did my windows build the vignette wasen't there.
I used VR Tunneling pro too but it was super buggy and I couldn’t figure out why. Like it would unexpectedly turn off. Have to follow up about that. I was using the mobile shader version with URP.
