Proportional editing creates rough edges around shape I'm trying to create a simple mountain with proportional editing, and I'm finding that it's creating unusual faces around the edges of the surface.  What I was hoping to do was to create a bell curve-like surface that is smooth around the entire surface.  However, what's actually happening, is it's becoming almost like an umbrella:



What rule does this follow, and is there a setting that can be changed to create more faces (almost like a subdivision, except on the proportional editing)?

I did use the Connected proportional editing mode, mainly because if I use Projected it comes up with a different kind of shape based on the projection of the camera (which seems fitting).
Your proportional editing is set to connected.



You can change it to Projected (2D) to get your desired result.
