Hello there! Whenever i try to make erosion on some smaller part of terrain like 10-50 meters for example the erosion node acts very strange adding some high frequency strong noise in everything. The Debris Flow Smooth button helps a bit but wonder why is this happening and how can i control this effect? Is there a global scale multiplier or similar perhaps somewhere? Cheers
I think this underlying noise problem with terrains is just there, and we all deal with it. You might want to try eroding at the default size, then use a couple of CLIP nodes to reduce the terrain to your target size.

To me this is the expected behavior when working with noise displacement, so as you decrease the element size, you normally also decrease the amplitude of the noise.
