With monkey head, Edit Mode: 1) when I selecte my four faces [3] if I want ONLY these four faces to be smooth...do I select Shade Smooth or Shade Flat? 2) How to make the the OPPOSITE happen when I select these four faces? .....meaning to make the rest of the monkey be smooth while keeping the four selected faces sharp? 3) To control the sharpness of the entire individual faces , do I use edges [2] or is this accomplished using Object mode, object, shade auto smooth where I can adjust the degree of sharpness?
