I've followed the use of Unreal as the render endpoint in animated film for some time – specifically, Epic's use of it themselves in their cinematic trailer in 2017:
Other indie filmmakers have also used Unreal this way, eg.:
While Unreal is capable of producing obvious quality:
... Eevee is also capable of some great stuff too:
So..., can someone explain to me how Unreal's render engine differs from Eeevee in render quality and speed?
- Are they different technologies?
- Is one faster than the other?
- Does one produce different quality than the other?
(I'm curious about this because if Unreal produces very similar-quality output in the same amount of time, the advantage would be to keep everything in Blender, obviously, to avoid the work involved in shuffling everything off to another application just to do rendering. If, however, Unreal offers great advantages, the work would be justified.)
