                <p>The PolyBevel tool is also very useful when working with organic models. In this lesson, you will add several bevels to a face model that will help define the eye, mouth and nostril.</p>

                        <p>To complete this lesson, you will require the following lesson file:</p>

                        </p>

                        <p>This file includes the partially completed head model shown below.</p>

                    <li>
                        <p>Triangulate the area around the eye</p>

                        <p>Press <button>i </button>to go into the head object. Press<button> tab &gt; Polysplit</button>, click on the following three points then <button>RMB-click</button> to accept.</p>

                        </p>

                        <p>The goal is to bevel the centerpoint of these polygons. Triangulating the area around this point will help create a more detailed eye socket.</p>

                    <li>
                        <p>Bevel a point</p>

                        <p>Press<button> tab &gt; Poly Bevel</button>. Press <button>1</button> to change your selection type to <button>Points</button> and select the centerpoint of the triangulated polygons. <button>RMB-click</button> to accept then adjust the <button>Relative Inset</button> value either using the <button>MMB</button> value grid or the Parameter pane.</p>

                        </p>

                        <p>If you want to repeat then press <button>q</button> then press <button>4</button> to change to <button>Primitives</button> and click on the primitive in the middle of the eye. <button>RMB-click</button> to accept. After reshaping these points to form the eye socket you can come back and apply more bevels.</p>

                    <li>
                        <p>Bevel an open edge</p>

                        <p>Press <button>q</button> to start another bevel. Press <button>2</button> to change to edge selection then click on the first edge in the mouth area. If the red arrow is pointing in then press <button>r</button> to reverse it. Press <button>f</button> once to expand the edge selection. </p>

                    <li>
                        <p>Add another bevel to the mouth</p>

                        <p>To add another bevel, press <button>q</button> then click on one of the outer edges of the new mouth area. Press<button> l</button> to start an edge loop which will stop at the corner of the mouth. <button>Shift-click </button>on the next edge then press<button> l </button>to finish the loop. <button>RMB-click</button> to accept then adjust the <button>Relative Inset</button>.</p>

                    <li>
                        <p>Create the nostril</p>

                        <p>Tumble the view to look up the model's nose. Press<button> tab &gt; Poly Extrude</button> then press <button>4</button> to chose <button>Primitive</button> selection and select the two faces under the nose. <button>RMB-click</button> to accept then before dragging the handle, <button>RMB-click </button>on the handle and turn off <button>Local Control</button> for the handle. This will let you manipulate the two faces as one. <button>Scale</button> the faces in then press <button>q</button> and <button>RMB-click </button>to create a second extrusion. Push this up along the Y axis to form the nostril. You may also want to scale it down.</p>
