That blueprint stuff is awesome! I just started watching videos about it and making dynamic lights switching on and off for actors moving into a volume is really a snap, done in just a few seconds, without coding something.
I also liked examples where you could see someone doing a simple arcade game like space invaders. It really is a powerful feature and I guess the only problem about it is to stop yourself from using it for anything as its performance while not terribly bad is not the best either...
