MR support in Unreal VR preview?

Hey all,
I’m about to upgrade my VR setup with a new Headset (I have a DK2) for my “on the move” presentation for work.
I was wondering if the new MR headset (any of them) is supported when pressing the VR preview button in the Unreal Editor, or in a near future feature (maybe 4.19) ?



I haven’t seen any official statements, but my perception is that WindowsMR is supported through SteamVR.

I’ve been seeing people having distortion issues with 4.18, but those should be remedied with 4.19.
