(This area is unavailable
until a keyframe is selected.) Here, you can set the value of a selected keyframe and adjust
its pre- and post-behaviors. For example, suppose that you have created a spinning globe
that takes 200 frames to make a full 360-degree revolution. Your total scene length is 600
frames, and the globe needs to rotate throughout the animation. Instead of setting additional
keyframes for the globe, you can set the post-behavior to repeat. After the globe
completes its 200 frames of motion, the Graph Editor??™s post-behavior takes over.You can
also set pre-behaviors. A pre-behavior is what happens before the first keyframe. You can
set either pre- or post-behaviors to the following settings:
?—? Reset, which reverts the current value to 0.
?—? Constant, which holds a values equal to the first key??™s value in a pre-behavior, the
or last key??™s value in a post-behavior.
?—? Repeat, which replays the motion from the first keyframe to the last for the duration
of the scene.
?—? Oscillate, which repeats a channel behavior from the first keyframe to the last, then
reverses it from the last keyframe to the first, for the duration of the scene.
