With Parameter Curve Out-of-Range Types you
can specify how an object is to behave outside the
range of the keys you’ve defined.
Use Parameters Curve Out-of-Range Types to
create loops and cycles. The idea is to create a
short pattern of keys that produce an animated
effect, and then loop or cycle through those keys
throughout the animation.
Using the Parameter Curve Out-of-Range Types
dialog, you select from four ways for repeating
your animation and two ways for applying a linear
value.
Tip: Use the Create Out of Range Keys utility (page
2–562), found in Track View Utilities, to turn the
parameter out-of-range animation into editable
keyframes.
