What you're about to witness is the next best example of why virtual reality changes the way we'll perceive the world. Inside the Unreal Engine 4 VR editor, users will be able to manipulate everything around them inside a virtual universe. What's more - this isn't like Minecraft, where everything is boxy. This is an Unreal Engine 4 environment. That means realistic. That means so realistic that we're leaping over the uncanny valley. It's done being creepy and we're straight away into The Matrix.
