I'm trying to learn subdiv modelling, but now I'm facing with some issues. That is clear, when I want to sharpen an edge or a corner I have to use support loops. My issue is: when I do that, support loops also running over areas where I would like to have smooth surface. Tried to even out edges, but the distortions are still visible on the smooth surface.
Is there a way to fix this without using edge creasing or bevel? (producing unnatural results or too sharp edges,but maybe I'm doing it wrong)
