For some reason my rift has stopped working after updating to 4.11.1. VR preview is greyed out and I can’t launch in VR after packaging either. Will update when I find a solution.
FIX: Delete your current run time and sensor drivers, download and install Oculus home. then in settings go to general and toggle the allow unknown sources option.
If you are using a DK2 just skip all the sections inquiring about controllers and the new sensor. There are some weird issues with using the DK2 with 1.3.0 though.
