That build only works on Oculus. Found out from your test. Made a new build that should work on all headsets. https://heartingninja.itch.io/vr-vein-ripping
Really hard to test how VR games work on other headsets without others trying. Hope you give it another go to see if my fixed worked.
The problem was when making the game if I had OpenVR Loader checked I would get an error while testing. So only used the Oculus plug in. I enabled OpevVR Loader and rebuilt the game. Was working for me and I hope it works on all headsets now. Made it under a new page because I was afraid butler would override old file and disqualify me.
