Speaking of working hard. I’m testing a scene to make some still images 100% made in unreal. It’s not going to be a playable scene but I want to see if I can reach vray’s quality for standard renderings. It’s actually quite easy and fast to make a scene for pre-dertermined camera shots. I’m using very very little geometry, 2d trees/plants but where the fun begins is with materials and effects. Adding fog, dynamic sky, emissive materials, water with screen space reflections, vertex painting, world displacement for materials, look up tables, all eye candy and get instant feedback is sooo much more fun than doing it the traditionnal way. Also, I made a 12 000 ish x 7 000 ish screenshot instantly!!! I’ll post result soon. This is a process of only a couple of hours. Want to see how fast it’s possible to make a good looking still from the modelling to the final screenshot! Also started to use procedural PBR substance materials. They look so good, especially when you add world displacement! 
I want to replace vray/corona with unreal for good!
