-'''Node Description and Purpose:''' Heightfield Erode simulates the natural effects of weather and water flow. It creates a realistic weathered effect on a heightfield, useful when enhanced realism is needed. The result is similar to many other erosion filters in dedicated heightfield editing applications. Controls are provided to customize the effect.
