Norwegian fjords

Hey guys, I’m wondering how to create fjords. Any tips please? I have also Geoglyph 2 tools. Thanks for any hints .)

If you don’t need them too detailed(you aren’t going to see them up close) I suggest just using meshes. You can model fjords fairly easily in Blender, or if you are using Unreal Engine 4 you could use the rock mountain models provided by Epic.

If for some reason you need the heightmap itself, then I suggest you modify the Mesas example and see if you can get something like Fjords.
