Creating a self-animating shape
Wiggle Paths is a path operation that turns a smooth shape into a series of jagged peaks and valleys. You’ll use it to make the star shimmer a little. Because the operation is self-animating, you need to change only a few properties for the entire shape to move on its own.
Expand the Star 1 layer in the Timeline panel, if it isn’t already, and choose Wiggle Paths from the Add pop-up menu.
Press the spacebar to play the movie so you can see the effect. Press the spacebar again to stop playback.

The star’s edge is too jagged. You’ll change the settings for a subtler effect.

Change Wiggles/Second to 5.0.
Click the Motion Blur switch (
