Ok, so i’ve been following create your first level tutorial that Epic created and it seemed to turn out all well and good, so I extended room and put in alot more windows. Unfortunately, entire area is pretty much black now. I get small points of light where directional light is coming through windows and is hitting ground, but there is no “bouncing light” that should be making rest of room brighter and I can’t figure out why. When looking in other projects, I see something called a light importance volume something or other but I am unsure if that is related at all, nor can i find it in light section on left in modes section. Normally, I would just wait for Epic’s eventual lighting tutorial release, but I would really appreciate if someone could enlighten me on this issue as I would like to have an area to test out builds that isn’t pitch black.
Hey Knobbynobbes,
Have you built lighting? Is your directional light still Static or have you changed it to Movable? Dynamic lights do not support bouncing, but Static and Stationary should.
Yea, my lighting is built and I checked my directional light and it is set to stationary. I tried changing it to static but that didn’t change anything. I did, however, notice that when i was facing a wall and not looking at any of windows or outside light sources, walls lit up closer to what I was wanting. It seems that there is some other process happening when i look out or even in direction of windows that is making everything else turn black.
Ideally, I would like my lighting setup to look like office blueprint example project that they recently released, and that project only uses a directional light for majority of its lighting needs (I checked room on left when you start and there is only a small point light that doesn’t make any difference in overall lighting if you delete it and rebuild lighting).
There is an automatic process for eye adaptation that is turned on by default, and that may be what’s happening here. Under Lit dropdown in Viewport, go down to Exposure and set it to Fixed at Log 0. This will disable eye adaptation process and may solve issue you’re encountering. Let us know if that helps!
Unfortunately, that seems just to have made things worse. Now everything is darker and looking only at wall doesn’t make it any brighter. Even area with point lights in it is really dim.
Ok, so after scrutinizing Office Project some more, I seem to have found a solution. I had to increase intensity of light source from 2.5 to 7 and indirect lighting intensity to 2, then to 3 cuz it looked even better. Also turned off “used as atmosphere sun light.” I then added a post process volume, set to unbound, and under auto exposure set min to 0.5 and max to 2. Now everything is nice and bright with some very pretty sunlight.
