I'm a beginner to UE4 and game engines in general. The area that I enjoy the most is the particle creation/VFX side. Beyond youtube videos and teaching myself I would some like more substantial tutorials. I've noticed that in general there's an abundance of UDK tutorials for the particle editor (rightfully so with it being older) and not as many for UE4. I was wondering if UDK tutorials are still relevant - mainly those found on 3Dmotive/ImbueFX before I spend money on tutorials? Thanks in advance.
