It's possbile and very easy. I just have to put one color for the land over the sea level.

You mean to flatten and then make all the elevation with FT ? Im not sure how to do that

Edit: Ok it's possible if I combine FT with Wilbur to flatten the land and then import it back to FT. It's true that the program tends to put mountain ranges at weird places.
So, based on the following map, where should the mountains be located? It's like asking: where are the tectonic plates ?
