Title: Smooth node
Post by: Leigh Kamraoui on May 30, 2018, 10:18:53 AM
Smooth node

The smooth operator produces geometric artifacts at exactly a distance "x" from the border where "x" corresponds to the size of the smooth filter. It correponds to a slight change of the derivative of the resulting smoothed terrain that is usually imperceptible except when extracting masks and especially using the curvature node.

A possible workaround is to generate larger terrains and crop the result.

Another possibility is to combine the curvature mask with a Painted Mask to discard the values near the border (see the  Curvature terrain example (https://www.wysilab.com/OnLineDocumentation/Examples/Examples_Curvature.html) for details).
