Thanks guys, this looks incredibly useful. Very glad I found this thread.
I’m an experienced C++ developer, but new to Unreal, and very keen to start messing around with VR stuff.
This looks like exactly the head-start I need.
(Haven’t been able to try it for real yet - although Vive arrived yesterday (Yay), I didn’t realise I was going to need a Display Port cable. (Boo)).
