hi there,
I got a little bit of a problem, may somebody like to help:
I got a pre-made terrain (heightmap) and I need to erode it a bit.
However, the mostly flat ground needs to stay untouched - the problem is, the terrain rises up from south to the north.

Now, as you can see on the image, if I would use erosion without any selection or masking, WM would erode everything, including the ground (see light-green lines)
I need a way, to direct erosion in a “diagonal line” across the terrain (see blue, dotted line).
Now - how can I get there?
Kind Regards!
I guess the image was lost during the upgrade/change to a different forum platform.
On a general note, what I’d do is erode everything, then use a combiner to combine the original and the erosion, with a mask to select where the eroded landscape is visible.
