Shaping the Nose
So far our nose looks somewhat shapeless, so let's add some geometry to refine the tip.
1. Select the faces that cover the tip and bottom of the nose and extrude them outward
(Figure 3.43).
While most games utilize textures to create the effect of nostrils on a character's face, it can
be useful to know how to create them with geometry.
