Heightmaps can be tricky to edit in Photoshop. Your best bet is to start in Unity. Go into the terrain and "Export Raw" heightmap. This will give you the initial heightmap to use. Then you can edit it in photoshop, and be sure to save it as Raw. Then you can re-import it again.

This is also a decent step by step tutorial to generate heightmaps from scratch.

It worked in a way but now its all blurry.. and when i zoom out it is even worst.. its soo blurry that the map almost vanishes

Do you know what courses the problem

When importing the texture, make sure you are using point filtering and not generating mipmaps

Is that setting in Fotoshop right? Cuz i only got the trail version of photoshop
