I am no stranger to the annoying Unity lighting glitch that makes all shadows sharp and absolutely black, causing a lot of frustration for developers. Usually however, this glitch does NOT show up in the game once a build is made, but all of the suddon it is for me! I am not sure what to do about it. I use realtime unity lighting with two directional lights. One of my scenes looks fine lighting speaking, but the main one is unplayable like this.
For anyone else who has this problem, I found a way to sort of fix it. I say sort of, because I didn’t actually stop the issue, I just balanced it out. The best thing I found is to just add Ambient light, which can be done by going to WIndows > Lighting, and then adjust the settings in that window.
