The Linear controller
interpolates between animation keys by evenly dividing the change
from one key value to the next by the amount of time between the
Linear controllers do
not display a properties dialog. The only information stored in
a linear key are the time and animation values.
Use Linear controllers
whenever you want a very regular, even transition from one key to
the next. For example, use a Linear controller for:
- A color parameter to change from one
color to another at a constant rate of change.
- Transforms to produce mechanical, robot-like motion.
To assign a Linear controller:
- Select an animated object.
- On the Motion
panel Parameters Assign Controller rollout,
select the Position track in the list window.
- Click (Assign Controller), and
then select Linear Position in the Assign Controller dialog.
The animated object has
a mechanical motion.
You can also assign this
controller in Track View.
No Properties dialog
is available for Linear controllers. You can, however, move keys
in Track View to change the animation.
Change linear key time. Move
keys horizontally in Track View Edit Keys or Function Curves mode.
Change linear animation values
by moving keys vertically in Track View Function Curves mode, change
the parameter value in the viewport with Auto Key on.
