Just as child objects depend on and move with their parent objects, ???child???
bones are controlled by parents and can be used to set up subtle or complex
object deformations.
3. With the first bone selected, click the Child Bone button. Click OK because you
don??™t need to set a name when the requester asks you to.
You??™ll see a bone attached to the end of the previous bone (Figure 12.3).
Figure 12.3 You can add child bones to create a hierarchical structure.
4. Add one more child bone as you did in Step 3. A quick way to add child bones is
to press = (the equal-sign key). After it is added, select the first bone and rotate it.
Press the up-arrow key twice to change the selected bone.
When the parent bone rotates, you??™ll see the child bone rotate as well. If you select
and rotate the second bone, its child bone rotates, too.
This hierarchical structure is explained in detail later in the section ???Creating
Hierarchies.??? For now, you can think of this structure as similar to your own arm.
The shoulder is connected to the upper arm, which is connected to the forearm,
which is connected to the hand, and so on.
