I know that we still lack a proper map editor and are left out to using for instance https://www.transportfevermods.com/en/mapcreator.html. At the same time, i know that you can run the game with the no costs mod and adjust hights and smooth things out, add trees and stuff like that in-game. But then, this can not be saved to the "map" but just to your own save game right? Would be great if this could be elaborated by the pros on map creation.

Another thing on heightmaps, when I get a heightmap the sea level is set to "0", but lakes up in the mounainous areas are much higher up than that, but if I want water in the mountain lakes I have to lower the to sea level, meaning they will get steep cliffs from the surrounding grounds. If i raise the sealevel to compensate instead, i flood the grasslands close to the coast. I guess there is no solution to this?

I have a desire to do a map of the north of Sweden or perhaps the Bothnic gulf but my attempts so far has been far from satisfactory, even though I have followed availible guides and used heightmaps, GIMP and so on. For instance, I would need to cover the ground with about 80 % trees to make things realistic.

Thanks for your time!
