In a fresh project in 5.6 I created a new map with the Open World map as the base. I modified it slightly using the sculpt brush to lower portions of the center areas so it’s not all flat. That worked fine. Now I’m trying to flatten out an area at the top of a hill, and it won’t work. The flatten tool is actually adding hills which I’ve never seen before. I switched to the ramp tool, and it’s either carving a big tunnel or raising a peak depending on the direction of the two points. What’s going on?
