How to restrict proportional editing of vertices to an edge loop? I am trying to model a fat guy and need to adjust an edge loop to better fit around his gut. I want to use proportional editing but only have it affect vertices on the edge loop. How can this be done? This is not the most pressing example but I will require smoother adjustments soon.
Select your edge loop, shift H to hide the other vertices, then play with your edge loop, and when you have finished, alt H to make visible again.
