Apply - Ease Curve and
Apply - Multiplier Curve (available from the Curves menu in the
Curve Editor) create an ease curve or multiplier curve track. These
tracks let you modify or intensify an existing animation track without
changing the original track.
- A multiplier curve shifts the value of
the original track up or down.
Adjusting the multiplier
curve increases or decreases the “intensity” of the original track.
- An ease curve shifts the time of the
original track left or right.
Adjusting the ease curve
changes time. The value of the ease curve at a particular frame
is a frame value from the original track. For example, if the ease
curve is 0 at frame 0 and 10 at frame 10, the original track plays
at its original speed. If the ease curve value at frame 10 increases
to 20, the original track plays to frame 20 by frame 10: it has been
sped up by a factor of two.
Once you apply an ease
or multiplier curve, you can edit its keys, ranges, and properties
just like any other animation track.
One use of ease and multiplier
curves is to blend between the effects of different controllers.
This can be an aid to nonlinear editing.
To apply an ease curve or a multiplier curve:
- In the Curve Editor Hierarchy list, highlight
the tracks you wish to ease or intensify.
Not all controller items
can receive ease or multiplier curves. For example, the Path Constraint
position controller cannot receive an ease or multiplier curve,
but its subordinate Percent controller can. If the highlighted controller
is incapable of receiving ease or multiplier curves, nothing happens
when you apply the curve.
- From the Curves menu, choose Apply -
Ease Curve or Apply - Multiplier Curve.
- In the Controller window expand the highlighted
tracks to view the ease curve.
- Hold down the Ctrl key
and click the ease curve and controller tracks.
- Adjust the keys on the ease curve and
watch the result in the controller curve.
Use a Multiplier curve
to intensify an effect, or an ease curve to make less of an effect.
TipUse Step interpolation
to use the ease curve to turn tracks on and off.
- Apply - Ease Curve
Applies a curve to alter the
timing of the selected function curve. Ease curves vary the timing
of a superior function curve. A normal function curve charts an animated
parameter value over time. An ease curve charts changes to the timing
of a function curve over time.
- Apply - Multiplier Curve
Applies a curve to scale the
value of the selected function curve. The value of a multiplier
curve is a scale factor applied to the value of its superior function curve.
You apply ease and multiplier
curves in Curve Editor mode. Once you apply an ease or multiplier
curve, you can edit its keys, ranges, and properties, as with any
other animation track.
