TIMELINE • 1001
You can use Time tracks to control any type of parameter that can be interpolated. There are almost
endless possibilities, from candles that icker to a Twist object that rotates a head slowly at the start
and end of the turn and quickly in between.
Example
 Create a sphere and animate its position along the X-axis so that at frame
0, the sphere is at X=0, and at frame 90, it’s at X=300. The Timeline should
then look as follows.
 In the animation toolbar, click the Play button to play the animation. Click
Stop when you are nished.
The sphere moves with the same speed from start to nish.
 In the Timeline, with Sphere selected, choose File > New Track > Time to
create a Time track.
 Ensure that Sphere is still selected in the Timeline. Alt-click the sequence
for the Position.X track to display its Sequence Properties in the Attribute
manager.
 In the Attribute manager, you’ll nd a box called Time Track. Drag the name
Time from the Timeline and drop it into the Time Track box to assign the Time
track to the Position.X track.
