Unreal Engine 4 AR Test
A Hungarian company (unreal4ar.com) released an AR plugin for Unreal this week using the AR Toolkit for recognition. This is the first AR plugin I know of on UE4. Recognition was sub-par to some of the early Vuforia/Metaio QR code/Image recognition. ARToolkit is a couple years behind, but what's cool about this is that all of the Unreal visual effects translate to the viewers camera nicely, so lens flares and glare on augmented objects as well as some attempt at shadowing.
