Range Display
After you synthesize the Master
Motion Clips, displays delegates minimum,
average, and maximum acceleration.
MinSet a minimum acceleration value for the
range.
Max—Set a maximum acceleration value for the
range.
Unique—Choose Unique to have the motion
sy nthesis eng ine activate the clip when the
delegate’s acceleration matches a specific val ue,
optionally with a rising, falling, or constant value
before or after the specified value.
Value—Set a unique acceleration value.
In/Out—

Anythi ng—Acceleration before or after the target
value is not relevant.
Decreas ing—Acceleration decreases before or after
it reaches the target va lue.
Co nstantAcceleration before or after the target
value is constant.
Increasing—Acceleration increases before or after
it reaches the target va lue.
Scale Playback Speed group
Thesesettingsletyouscaletherateatwhich
the animation is played, depending upon the
acceleration of the delegate. By default, when
Scale Animation is off, the object animation will
always play at its normal rate. If you turn it on,
you can then set a Base Acceleration, at which the
animation should play at its normal rate, plus a
percentage to specify how much the animation
rate is modified by the actua l delegate acceleration.
Scale AnimationScale the clip’s animation based
on acceleration.
Fo r example, as a bird accelerates, its wings beat
more rapidly. Scaling an animation scales the keys
of the animation.
Percentage—Specify how much to alter the
play back speed based upon the difference
between the delegates acceleration and the Base
Acceleration setting.
The formula used is this:
Animation Speed change % = (current speed/Base
A cceleration -1 ) x P ercentage %
For example, if a delegate is accelerating 50 percent
faster than the b ase acceleration, and the Scale
Percentage value is 50, then the play back speed is
scaled up by 25 percent.
Base AccelerationSpecifies the delegate
acceleration at which the animation should be
played back at its normal rate.

To have delegate pitch considered for mot ion
sy nthesis, turn on Use Pitch, choose R ange or
Unique, and then make the appropriate settings.
Pitch is determined by the angle in degrees of
the delegate about the world X-axis. In world
coordinates, the delega t es pitch is positiv e when
it’s aimed upward, negative when it’s aimed
downward, and 0 when it’s aimed parallel to the
home grid.
