So I have been experimenting with blueprints in Unreal Engine 4 and have found myself short of learning material. I have checked everywhere to obtain new tutorials and information to broaden my horizon. I have checked out a lot of youtube videos and have swept through their website and cannot seem to find anything new that I have not already mastered. Is there a series of tutorials anywhere with a price on them that I can easily pay for to truly master blueprints or something of the sort?
