I just made my own heightmap in GIMP. However it was very rough. So I applied some blur to it. The result was this:

As you see it is first completely flat. Then goes down one step. I assume my way of smoothing out the terrain was wrong. So how do I smooth it out correctly?
From the TerrainTestAdvanced.java file:
[java]
heightmap = new ImageBasedHeightMap(heightMapImage.getImage(), 0.5f);
heightmap.load();
heightmap.smooth(0.9f, 1);
[/java]
Thanks for a quick response Works nicely.
