Last year, Epic Games Chief Technology Officer Kim Libreri and Unreal Engine 4 General Manager Ray Davis visited some friends at Lord of the Rings effects studio Weta Digital in Wellington, New Zealand. They only wanted a tour of the studio, but along the way they ran into Weta's head of R&D, Alasdair Coull. He mentioned that he was messing around with Unreal Engine 4, Epic's game development platform. Fast forward to March 2015: Epic Games and Weta are showing off a virtual reality demo featuring the greedy dragon, Smaug, swimming through mountains of gold in the second Hobbit film, voiced in all his baritone glory by actor Benedict Cumberbatch. Smaug speaks directly to the person in the headset -- Oculus Rift's Crescent Bay model -- and his daunting size is on full display. Five hundred feet of red-scaled, deep-speaking Smaug.
