Terrain generation solution? see inside

Hello, guys. I’m kinda stuck here.
Problem: I’m making a fishing village, and the map is ‘divided’ into two parts: ground with houses, trees, etc, and the other one is beach, descending under water.
I don’t want to edit it manually, like, lowering one part and hightening other, 'cause it looks dull - I’m no good as terrain designer.
Can I make Terrain Toolkit somehow generate terrain, one part of which will be lower (below sea level, so to say), and the other one will be above?
Or can you suggest any other terrain generation tool for making this?!

I attach the image of how it should look like (just for you to have an idea), but you know, more detailed and live :smiley:

USGS has a huge library of real world elevation files. Probably no one will mind if you import a section of their beach.

Note that it’s probably also worth investing some time in learning how to use terrain painting tools. They aren’t so bad and you can get good results directly in unity with a few hours of practice.

The only thought I carried out after trying out few terrain generators:

It’s better to spend some time with unity’s default terrain tool, than learning how to use other terragens
