VR support was intended to have its own 3D menu, by not using UMG (or with 3D umg elements if it’s stable enough).
It was put on hold since Gamesettings needed a large rewrite to support multiple menu systems.
That rewrite is done now, together with this keybinding system. I also assume the editor crashes way less now then before, so it might be more fun developing without losing work ;D
The main new features of a 3D menu would be gamepad navigation support and animations. I can assume it will work in VR headset, but I don’t have one to test it with for now, so I can’t guarantee that it will work.
Back in unreal 4.8 I tried the 2D UMG Settings in a vr headset, and it was not usable. It might be better now since 4.11/4.12 have huge support for VR, but you have to test that one out yourself.
