That is the only thing I haven’t figured out about modelling is when you smooth a grid of quads that are all odd sized throughout a curved shape as you smooth you lose volume as he shortest path between 3 vertex in a curve is a straight line. But that is not what I want. I want to smooth vertex in order to have a rounder shape.
What I do now is eyeball it and fix, repeat over and over.
So how do you do it? Is there an addon?
