Hello
After some time i finally decided to release my HeightMap editor. I decided to release it as freeware with optional donations.
Zemnik is a HeightMap Editor for small to medium-size HeightMaps. Maximum tested safe working size was 12000x12000 (depends on RAM size). Zemnik comes with many build in functions for manual HeightMap editing. Zemnik supports per-vertex and per-pixel texturing with maximum of 255 different textures. Maximum tested per-pixel texture size was 7000x7000 (depends on RAM size). Zemnik also allws you to place markers with text, position and orientation on your map. With the ability to place 3D models it could be used as map editor for games. Last, but not least, Zemnik can load already created HeightMaps, and use them as models.
Zemnik uses DirectX 11 for rendering so it's for Windows only although maps and other files created with Zemnik are usable in any other application. After downloading Zemnik you can find c++ header and source on how to load and use Zemnik HeightMap files. It also contains HLSL example of how Zemnik HeightMaps are rendered with DirectX.

This is the very first project i officially released so i'm sure i made some beginner mistakes. If you find any bugs or something that should be different please post it here.
I made a short video on how make a simple map with Zemnik:
