Can't get a working orthogonal camera

I want to make maps in style of Baldurs Gate/Pillars of Eternity, which were a isometric 2D backgrounds. This is example

I’m trying to do the same in UE4, however:

  • standard camera in orthogonal projection doesn’t show lights (spot/point lights)
  • Cine camera doesn’t have orthogonal projection
  • viewport options have only perspective projection and orthogonal views are top-down and sides. Sort of workaround is to put lowest FOV (5), but on big maps, the perspective discrepancy would be visible

I’m there stuck - I don’t have ideas how to tackle this problem. Plugins maybe? Some workaround, fixes?
