Straight lines in erosion pass

I have a channeled erosion that is making a lot of really straight lines where there weren’t in the underlying geometry. It just cuts in a long straight channel that has rather geometric channels coming off of it. Am I missing some kind of setting or trick? It’s not everywhere, but it probably represents 90% of the channels I’m getting.

Hi there,

Check if you’re using the “inverted filtering” setting. This often is the cause of the long straight channels when they occur.
