refer to directions from Jackie’s point of view, not from your view of the
scene.)
As mentioned before, when you move a joint, all joints lower in the
hierarchy move with it. If you press Insert (Windows and Linux) or Home
(Mac OS X) while a joint is selected, you can move the joint without
moving joints below it in the hierarchy. (To exit this mode, press Insert
or Home again.)
NOTE You may need to rotate left_hip so that the skeleton fits inside the leg.
It’s unnecessary to fit the skeleton perfectly inside the character, as it won’t
be displayed when you render an image from the scene.
8 To create the joints for the other leg, you can save time and ensure
symmetry by duplicating the existing leg joint chain with mirroring.
With left_hip selected, select Skeleton > Mirror Joint > . In the options
window, turn on YZ for Mirror Across.
Jackie’s legs straddle the YZ plane, so mirroring the joint chain across the
YZ plane positions the duplicate joint chain in the desired location. This
operation illustrates that Jackie’s original position affects the ease with
which you can create the skeleton. Had Jackie been positioned away from
the origin, you would not have been able to use Mirror Joint conveniently
to duplicate the leg’s joint chain.
9 Enter left in the Search For field and enter right in the Replace With field.
The Replacement names for duplicated joints feature automatically
replaces the names of all duplicate joints with the specified joint prefix.
10 Click the Mirror button.
The right leg bones and joints appear in a mirrored position.
