It was one of my friends who introduced me to unreal engine casually four to six months ago and showed me some of the interactive stuff that was next to impossible in traditional architectural workflow (Vray and 3ds max). Inspired by the demo shown by the friend I dedicated some of my time to the research and development in exploring the possibilities of unreal engine in architectural visualization. C&C are welcome. Hope You enjoy. Thanks.
