Newsbrief: Unity has long been teasing an updated UI creation system for its engine, and it's almost here. While the highly anticipated system didn't quite make it into the recently released 4.5 update, it's almost ready -- enough to showcase it in a nearly half-hour long demo. Above, Unity developer Rune Skovbo Johansen demos the new system in detail -- you can watch him create UIs that are either in screen-space or in game-space, and also see how the system interfaces with other parts of the engine. If you've been anticipating this new system, it's worth a glance.
