Ring Array System 415
This option is available only if Bone On is on.
Default=on.
Note: Changing the Auto-Align state does not
have an immediate visual effect on the skeleton. It
affects future behavior when bones are moved.
Correct N egativ e S tretch—When turned on, any
stretching of the bone that results in a negative
scale factor will be corrected to a positive number .
This option is available only if Bone On is on.
Default=on.
Realign—Causes the bone’s X axis to realign and
pointatthechildbone(ortheaveragepivotof
multiple children). Normally this alignment
is maintained, and there is no need to use t his
option. Ho wever, it is possible for the bones to
come out of alignment by tu rning off Auto-Align
andmovingachildbone.UseRealigntoalignthe
bone back to its child. This option is available only
if Bone On is on.
Reset Stretch—Stretches the bone to reach its child
object if the child has been moved away f rom the
bone. This option is available only if Bone On is
on.
Reset Scale—Resets a stretched bone’s internally
calculated scale to 100% on each axis. Using this
option avoids unexpected behavior due to objects
which are both linked and scaled. This option
has no visual effect on the bone. This option is
availableonlyifBoneOnison.
Stretch Factor Information
Under the Correct Negative Stretch options is a
text display giving information about the number
of bones selected and the respective stretch factor
forallthreeaxes.Ifmorethanoneboneisselected,
the Stretch Factor text displays undefined.
Note: The Stretch Factor text only updates when
you are in Bone Edit Mode (page 1–411).
Stretch and Axis Options
Stretch—Determines what kind of stretch takes
place when the child bone is transformed and
Freeze Length is off. Default=Scale.
•
None—No stretch takes place.
•
Scale—Lets the b one scale. The st retch happens
along one axis.
•
Squash—L ets the bone squash. The bone gets
fatter as it gets shorter, and thinner as it gets
longer.
Axis—Determines the axis used for the stretch.
•
X/Y /Z—Choose the axis for scaling or squashing.
•
Flip—Flips the stretch along the selected axis.
Ring Array System
Create panel > Systems > Ring Array button
The Ring Ar r ay object consists of a dummy object
(page 2–16) surrounded by a ring of boxes. You
can arrange the boxes in the ring along a sine
curve, vary their number, and animate the ring
array’s parameters. You can also replace the b oxes
w ith other objects using Track View, as described
in the Procedures section, below.
