			The smoothing effect is independent from the heightfield’s resolution, whether expressed as the “Number of points” setting or the number of pixels in an image file. What matters is the distance in meters which is based on world space. Notice in the example images below that although the heightfield resolutions are very different the final smoothing across the terrain looks very similar.
