I'm experimenting with some thick bunker lips for my Australian sandbelt look, and I really like the effect I am getting here, especially after I lower the terrain, but a lot of the bunkers have a few jagged artifacts like this one in places:

..
No amount of smoothing even at 100% strength seems to be able to get rid of these entirely.... is this just a matter of smoothing more and more and more until it goes away, or is there a setting that might get rid of it?
I'm not using any "pot" bunker setting; just regular settings with the lip thickness at about 0.22.
