Weird shadows after lighting bake

Hello. i’m working on a prototype drive-in scene right now and everything is going ok except for the shadows. When i bake the lighting i get these results:

i have heard that i need to change the lightmap res, but i don’t know where or to what value change them. Could it be my terrain? it’s created in ue4 btw.

Your landscape should have a ‘Static Lighting Resolution’ value in it’s details panel. Try increasing that value. Be careful not to set it too high as it can drastically increase the baking time and hit performance pretty hard.
