Concrete (CNCT) is basically rock. But...i don't see any uses for this, i mean, you can already simulate Wind Erosion by making a nice hill of SAND, if the velocity is strong enough it will pick up some SAND and deposit them somewhere.
@asdf123(View Post) If you're suggesting this as an element, no, just like equals said, there's no uses for erosion
If you're just stating facts about erosion, yes, rock wears away after hundreds of thousands of years of water flow, ever see the grand canyon or Niagara falls?
