Coarse Anatomy
With our planes sketched out, we can move on to
further defining the anatomy. References are par-
ticularly handy at this stage as we define further
anatomical details using brushes like Clay, Clay
Tubes, Crease, and Inflate to accentuate individual
muscles and the bones of the body and the face (see
Figure 6-22).

Sculpting Hard-to-Reach Areas Using Shape Keys
Some areas, like under the armpits or between the
legs, can be awkward to reach with your sculpting
brushes. To make the task easier, create a new shape
key for your mesh in Edit mode that will let you
reach the area you want to work on.
Shape keys allow you to store different posi-
tions for the vertices of your mesh, enabling you, for
example, to have one position with the arms up, one
with the arms down, or whatever position you wish.
Shape keys are fully compatible with Sculpt mode,
meaning you can blend them on or off to change
your sculpt's pose while sculpting. For example, for
this sculpt, I created shape keys with the character's
arms and legs held further out to make it easier to
reach the armpit and inner leg areas.

holding down D and clicking to draw. Now you can
sketch any anatomical landmarks on your sculpt
before actually sculpting them in. For example, in
Figure 6-21, I have sketched out the major muscle
groups.
