But it appears that the mountains are exclusive. Different mountains can be placed on top of each other, but only inside the boundaries.
If I want to place them close together, even more, to make them touch and fade, this is not possible at the moment.
Because when a mountain is placed across another, the old mountain is removed there, and this causes gaps down to the ground level between the two mountains.
Therefore I suggest to have a gapless terraforming, or additional decoration blocks that allow to close that gap.
