The avalanche brush allows you to apply natural-looking cracking/tumbling erosion to areas of your map. Avalanche removes material from steep areas of your map, and allows it to tumble downhill until it settles at a flat spot. An example is shown below:
The avalanche settings are as follows:
Label | Default value | What is it? |
---|---|---|
Min. slope (deg) | 10 | The terrain slope angle, in degrees, above which tumbling will take place. |
Run length (px) | 2 | The maximum distance, in pixels, that material can tumble in the avalanche calculation. Use small values (5 or less) for simple smoothing, and large values (50 or more) for realistic cliff/valley erosion. |
