much the animation rate is modified by the actual
delegate speed.
Scale Animation—Scales the clip’s animation based
on speed.
Forexample,asabirdincreasesitsvelocity,its
wings beat more rapidly. Scaling an animation
scales the keys of the animation.
Percentage—Specify how much to alter the
playback speed based upon the difference between
the delegate’s speed and the Base Speed setting.
The formula used is this:
Animation Speed change % = (current speed/Base
Speed -1 ) x Percentage %
For example, if a delegate is moving 50 percent
faster than the base speed, and the Scale Percentage
value is 50, then the playback speed is scaled up
by 25 percent.
B ase S peed—Sp ecifies the delegate speed at which
the animation should be played back at its normal
rate.

appropriate settings.
Inter face
Acceleration is measured in units per frame per
frame, where the unit is the current 3ds Max
system unit. That is, the acceleration is determined
bytherateatwhichthespeedchangesperframe.
Use A ccel era tion—Tur n on to have the motion
sy nthesis eng ine consider delegate acceleration in
determining whether to activate the state.
Range—Choose Range to have the motion
sy nthesis e ngine ac tivate the clip w hen the
delegate’s acceleration falls inside the specified
range.
