I am trying to trim all of the vertices or faces off around my displacement, which I applied to a plane. The vertices on the plane are not at 0, so even though they look flat around the main image they aren't completely, they didn't move too much though. Is there a way to select vertices that are less angled than others? I tried sharp edges, but I can't select the rest of it, because it starts to select all that I don't want too. Or maybe a way of conforming the flatter vertices toward the middle? This image doesn't have alpha. Just trying to "carve" my image displacement out without a lot of manual work. Then extrude it to a mesh. Thanks!
