I have created a random map with foliage. And I wanna improve this map by replacing some foliage with other one. So I just duplicate the same map. My problem is that when I duplicate the map, lighting or shadows goes bad without changing anything and I don’t know why. More specifically from the one side objects seem completely dark. In the first map all things are right but in duplicated map things go bad? Anyone has any idea? Pls help me!
First image is the normal map, and second is the duplicated one. I emphasize again that I make no changes. Any solutions pls?
