From the Cur ves menu choose On/Off.
If you also have the parent track selected (the

Out-of Range Types
Ease Curve Out-of-Range Types displays a dialog
that lets you assign out-of-range types for the
current
ease curve (page 3–1025) .
Ease and multiplier curves use the same
out-of-range types as other controller tracks.
See
Parameter Curve Out-of-Range T ypes (page
2–528)
.
You will usually want to use the same out-of-range
type for an ease curve that you use for its superior
function curve.
Procedure
To set the out-of-ra nge ty pe for a n ease curv e:
1.
Highlight one or more ease curve items in the
Hierarchy list.

Out-of-Range Types.
3. Do one of the following.
• Click an out-of-range type image to apply
that type to both the incoming and outgoing
curvesoftheeasecurve.
• Click the left arrow button below an
out-of-range type image to apply it to only
theincomingcurveoftheeasecurve.
• Click the right arrow button below an
out-of-range type to apply it to only the
outgoing curve of the ease 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.
Linear—Projects the animation value along a line
tangent to the ease or multiplier curve at the end of
the range. use linear when you want the animation
to enter and leave the range at a constant velocity.
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 between a forward 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 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.
