This problem is only occuring with foliage, The lighting is shining through to terrain and only on foliage, everything else is working.
Before you ask, yes I did enable two sided shadowing in the terrain and my directional light is set to movable.
Please explain to me why this is happening.
Am I just screwed? This post isn’t getting any views, so I should just give up with this engine if it has stupid lighting bugs that can’t be fixed, like this one.
What I have done to fix this, is turn off the “sun” light when it dips below the horizon. Or at least set it’s intensity to zero. You can use a timeline for this so it’s smoother by making a curve and setting it’s intensity to zero over time. I have that functionality in my level blueprint as all of my time of day settings are in there.
EDIT: I’m not sure exactly why this happens on a technical level, but I’m guessing it’s the way foliage is lit, and the fact that a little bit of the foliage is sticking underneath the surface exposing it to the light.
