Multiplier Curve Out-of-Range Types 563
Identity—
Projects the ease curve along a line with
a slope of 1.0 from either end of the range. This
causes time to flow at a normal, constant rate

non-repeating effect.
Identity for an ease curve produces an effect
similar to constant for other types of curves.
Identity is not available for multiplier curves; it is
the default Out-of-Range type for ease curves.

Ease and multiplier curves use the same
out-of-range types as other function curves.

Procedure
To s et t he out-of -r an ge ty pe for a mu lt ipl ier cur v e:
1.
Highlight one or more mult iplier curve items in
the Hierarchy list.

CurveOut-of-RangeTypes.
3. Do one of the following.
• Click an out-of-range type image to apply
that type to both the incoming and outgoing
cur ves of the multiplier curve.
• Click the left arrow button below an
out-of-range type image to apply it to only
the incoming curve of the multiplier curve.
• Click the right arrow button b elow an
out-of-range type to apply it to only the
outgoing curve of the m ultiplier curve.
Interfa ce
Co nstant—Holds the values at the ends of the
range for all frames. Use Constant when you
want no animated effect before or after the range.
Thetimevalueatstartoftherangeisheldforall
frames before the range, and the time value at the
end of the range is held for all frames after the
range. Constant is the default out-of-range type
for multiplier curves.
Cycle—Repeats the same animation as within the
range. Use Cycle when you want an animation to
repeat exactly.
Loop—Repeats the same animation as within the
range but interpolates b etween the last key and
the first key of the range to create a smooth loop.
Use Loop with an extended range bar to produce
smoothly repeating animation.
Ping Pong—Alternates b etween for ward and
backward repetition of the animation within
the range. Use Ping Pong w hen you want your
animation to alternate back and forth.
Linear—Projects the animation value a long lines
tangent to the ease or multiplier curve at the
limits of the range. Use Linear when you want
the animation to enter and leave the range at a
constant velocity.
