Range Display—
After you synthesize the Master
Motion Clips, displays delegates’ minimum,
average, and maximum acceleration.
Min—Set 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 engine activate the clip when the
delegate’s acceleration matc hes a specific value,
optionally with a rising, falling, or constant value
before or after the specified v alue.
Value—Set a unique accelerat ion 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 ta rget value.
Co nstant—Acceleration before or after the target
value is constant.
Increasing—Acceleration increases before or after
it reaches the ta rget value.
Scale Playback Spe ed 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 c an 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 actual delegate acceleration.
Scale Animation—Scale 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 delegate’s acceleration and the Base
Acceleration setting.
The formula use d is this:
Animation Speed change % = (current speed/Base
A cceleration -1 ) x Percentage %
For example, if a delegate is accelerating 50 percen t
faster than the base acceleration, and the Scale
Percentage value is 50, then the play back speed is
scaled up by 25 percent.
Base Acceleration—Specifies the delegate
acceleration at which the animation should be
played back at its normal rate.

To have delegate pitch considered for motion
sy nthesis, turn on Use Pitch, choose Range or
Unique, and then make the appropriate sett ings.
Pitch is determined by the angle in degrees of
the delegate about the world X-axis. In world
coordinates, the delegate’s pitch is positive when
it’s aimed upward, negative when it’s aimed
downward, and 0 when it’s aimed parallel to the
home grid.
