Thanks again man, exactly what I need. I`ll look in to NeoNaper's code to learn more about terraforming. But what I really need was the one Markus made.
The reason why it didn't work is because I used the A7 version of the DLL on A8 not knowing that there is a A8 version. Luckily Sivan uploaded the a mirror of the file.
I search the forum but it didn't showup for some reason. I also want to look into the Terrain Paint by Neo but the link is broken so I have to look somewhere else.
