Quote"Smoothed texture coordinates"The Compute Terrain node performs both of the above functions. However, when it calculates the texture coordinates it actually generates a slightly modified version of the coordinates which are later used for special effects in the Surface Layer, and these are the "smoothed texture coordinates".The smoothed texture coordinates serve as a smoother version of the terrain that can be utilised by the "Smooth effect" in the Surface Layer shader. These smoothed texture coordinates are also essential to the correct functioning of the "Intersect Underlying" feature in the Surface Layer. This is broken in the current public release (build 18.104.22.168) but has been fixed and improved for the next update.The scale over which the smoothing effect operates is controlled by the "patch size" in the Compute Terrain, and this therefore affects the results of the "Intersect Underlying" feature. I intend to provide some documentation on this upcoming feature when we release the update.
