Inter face
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
formultipliercurves.
Cycle—Repeats the same animation as within the
range. U se Cycle when you want an animation to
repeat exactly.
Loop—Repeats the same animation as within the
range but interpolates between the last key and
thefirstkeyoftherangetocreateasmoothloop.
Use Loop with an extended range bar to produce
smoothly repeating animation.
Ping Pong—Alternates between a forw ard and
backward repeat of the animation within the range.
Use Ping Pong when you want your animation to
alternate back and forth.
Linear—Projects the animation value along a line
tangent to the ease or multiplier curve at the end of
the range. use linear w hen you want the animation
to enter and leave the range at a constant velocity.
Relative Repeat—Repeats the same animation as
w ithin the range but offsets each repet ition by the
value at the end of the range. Use Relative Repeat
to create animations that build on each other as
they repeat.
Identity—Projects the ease c urve 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
outsidetherangeoftheeasecurve.UseIdentity
whenyouwanttheeasecurvetobealocalized,
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.

Curve Out-of Range Types
MultiplierCurveOut-of-RangeTypesdisplaysa
dialog that lets you assign out-of-range t ypes for
the current multiplier curve (page 3–978).
Ease and multiplier curves use the same
out-of-range types as other function curves.
You will usually want to use the same out-of-range
type for a multiplier curve that you use for its
superior function curve.
Procedure
To set the out-of-range type for a multiplier curve:
1.
Highlight one or more multiplier curve items in
the Hierarchy list.
2. From the Curves menu choose Multiplier
CurveOut-of-RangeTypes.
3. Do one of the follow ing.
• Click an out-of-r ange type image to apply
that type to both the incoming and outgoing
curves of the multiplier c ur ve.
• Click the left arrow button below an
out-of-range type image to apply it to only
the incoming curve of the multiplier curve.
