I googled anything i could think of, there are some similar issues but not really like this.
So, i'm working on my first terrain and i exported it for testing the clutter and in the map i noticed something strange
And in Bulldozer
The terrain is 1024x1024 by 10 in ASC format from L3DT.
I saw that other users have similar problem but with peninsula terrains, and they solved the problem changing something in the config.
How can i solve this? Do i need to go back to the start?
