I have a standard directional light with default settings and i have also applied a sky light so i have global illumination and all is fine apart from ceilings, for some reason there is no global illumination on the ceiling and it looks very dark.
Note- I AM NOT USING BAKED LIGHTING, my directional light is set to movable and so is the skylight
Here is a picture of my problem, this is not my picture but its the same affect
Distance Fields GI is seeing continual improvements as this is also being used with Fortnite. LPV on the other hand was some work that Lionhead Studios (Fable Game series) put in some work on.
