The latest podcast from chaosgroup (makers of vray) about VR. The challenges of storytelling in VR, mostly for arch-viz. They talk a bit about real-time and Unreal too because this is how to make the ‘‘ultimate’’ experiences. Interesting!

Thanks! I suspect you will be answering more and more questions from noobs like me soon! Hahahaha 
I’m still a noob but a noob who spend around 5 hours per day on Unreal engine.
I really want to make VR stuff soon but I don’t have a **** rift. If it was possible to get some kind of vr preview without the need of the actual device that would be nice. I could let the community test it.
