Future is near! 
It looks really cool, very high tech and Minority Report like :>
Although I can’t imagine making whole game waving my arms, it would be very tiresome. But if someone making enviroment or game for VR it’s amazing.
I see big potential for applications using this kind of technology.
I have couple questions:
1 New gizmo with bounds scale - will this be avalible in normal desktop editor? Espiecially bounds (stretch) scaling. That would be very usefull.
2 On stream you showed asset browser UI. Is it possible to make own 3D UI (like that asset browser) with UMG and use it in VR mode?
