I’ve attached a screenshot with my perfectly-working VR display mirrored to make it clear I’m not crazy. I understand that VR is supposed to “just work”, but VR preview is always grayed out. Was the same on 11.1 and the 10 builds I had (and I did have VR plugins enabled when I was trying that). My Vive works fine with steam apps, why can’t it do UE?
Did you make sure that steamvr was started BEFORE starting UE ?
Yep, tried it both ways around
This should work, if not you can change it back but go to Control panel → User Accounts - > Change User Account Control Settings and set it to never notify. Then run Epic Launcher as administrator.
Hope this works for you.
