The Smooth Height tool averages out nearby areas, softens the landscape and reduces the appearance of abrupt changes; it does not significantly raise or lower Terrain height.
Smoothing is useful after you paint with brushes containing high frequency patterns. These brush patterns tend to introduce sharp, jagged edges into a landscape, but you can use the Smooth Height tool to soften that roughness.
Adjust the Blur Direction value to control which areas to soften. If you set Blur Direction to –1, the tool softens exterior (convex) edges of your Terrain. If you set Blur Direction to 1, the tool softens interior (concave) edges of your Terrain. To smooth all parts of your Terrain evenly, set Blur Direction to 0.
The Brush Size value determines the size of the Brush to use, and the Opacity value determines how quickly the tool smooths out the area you’re painting.
