Overview
The Zero Edge filter sets the height of the edges of the terrain on the applied step to zero. By default, it is only applied on a lower level so you might have to take a look at the level step strengths to get your desired output.
Note that this filter operates based on a pixel distance, therefore lower levels will result in longer travel distances on the terrain, whereas higher levels will produce shorter smoothing distances.

- Smoothness
The range of the zero edge effect
