Dear rstralberg,
I have followed your instructions but was lost in some steps. I don't know how to export the height map in Terragen. The image you posted is really nice and good enough for my game which I am currently developing. Since I am using 3D Game Studio for game development, I am thinking of just using the terrain editor provided by MED to design the terrain (for example, how to draw roads and mountains, how to apply textures). However, I couldn't find any helpful tutorials of using this terrain editor.
Therefore, could you suggest any related tutorials of how to use terrain editor in MED?
Thank you very much in advance.
