Game engine is an art tool in the same way like Blender or Photoshop are. You have to learn its tips and tricks the same way artists do. Usually programmers consider anything that does not have a dedicated UI as fatal flaw hence all the bias towards big engines.

For example, you want to make and thumbnail picture of a 3d model/character. My first thought as a programmer on "correct" approach to that in UE was like well I need to setup a separate world with brand new lightning and have some renderer features off. The perfect "hack" for this is to have a separate "dressing room" under the level where the model teleports into and then back during single frame. Hundreds of such nuances can be only learned.
