To help you keep track of your adjustments to a keyframe or curve, a footprint cues
you visually to remind you how the item looked before you began adjusting it. A footprint
also lets you retrace your steps, or backtrack, if you choose to undo an adjustment. Follow
this next tutorial to learn more about footprints.
Exercise 6.8 Creating Footprints
1. Open Layout, clear the scene, and open the Graph Editor.
2. Select the light in the Scene window of the Graph Editor and drag it to the
Curve Bin.
All the motion channels for the light are added to the bin, as shown in Figure 6.46.
Figure 6.46 Selecting just the light from the Scene Display area and dragging it to the Curve
Bin adds all its motion channels.
3. Select the light Rotation.P, which is the Pitch rotation for the light. Of course, any
selected channel will do for this exercise.
When a channel is selected, you??™ll see it highlighted in the Curve Window.
4. Select the Add Keys command, the second small icon beneath the Curve Window,
and then click throughout the Curve Window to create some keyframes for the
selected channel. Figure 6.47 shows the channel with a few keys added.
