4 Now experiment on your own by moving individual vertices to shape
the nail and surrounding region as desired. A few suggestions follow:
■ In Smooth Shade display mode (Shading > Smooth Shade All), certain
vertices might be below the shaded surface and therefore impossible to
select and move. To display and select such vertices, switch to wireframe
shading (Shading > Wireframe). After selecting the vertices, return to
Smooth Shade display mode so you will be able to more easily see the
results of moving them.
■ You might get better results using the Move Tool’s default World setting
rather than the Normal setting made in a prior step. To return to the default
setting, select Modify > Transformation Tools > Move Tool, Rotate Tool,
Scale Tool, Show Manipulator Tool >
. In the Tool Settings window,
click Reset Tool, and then close the window.
■ To extend the front of the nail past the skin with a sharp edge, add a second
crease on the edges below the tip of the nail. (With the appropriate edges
selected, select Subdiv Surfaces > Full Crease Edge/Vertex.)
You might also want to add an additional level of vertices at the edges.
(With the appropriate vertices selected, select Subdiv Surfaces > Refine
Selected Components.)
After you crease the edges and add the extra vertices, you can make the
nail’s edge overhang the skin below it by dragging the vertices at the nail
tip out and away from the finger. Then tuck the row of vertices below the
overhanging vertices in the opposite direction.
An example of a completed nail follows:
1 If you want more practice, repeat the procedure for the rest of the nails.
2 When finished, select Modify > Transformation Tools > Move Tool, Rotate
Tool, Scale Tool, Show Manipulator Tool >
. In the Tool Settings
