Lesson 6. Station Identification > Animating a masked solid

Animating a masked solid

Masks applied to solids can be used to create quick elements for animation, like the eyes for the first cat on a pogo stick that jumps into the frame at the beginning. You will design a separate composition that contains the eye animation.

  1. Double-click in an open area of the Project window, select the CatPogo.ai file, and click Open. In the CatPogo.ai dialog box, leave Merged Layers selected and click OK.

  2. Select the Merged/CatPogo.ai footage item in the Project window. As you can see by looking at the information beside the item's thumbnail, the item is 393 × 692 pixels in size. You will create a composition that is slightly larger than the artwork.

  3. Create a new composition, name it Moving Eyes, set the Frame Size to 400 × 700, set the Frame Rate to 30 fps, and set the Duration to 7:00 (7 seconds).

  4. Drag the Merged/CatPogo.ai item from the Project window into the center of the Moving Eyes Composition window. Resize the Composition window so that you can see just the top half. If necessary to speed up screen redraw, choose Half from the Resolution menu at the bottom of the Composition window.

    To animate the cat character's eyes, you will create a solid black rectangle, and then construct an oval mask that will function as the pupil for the right eye (the right eye as you are looking at the cat). After setting Position keyframes, you will duplicate the layer for the left eye.

  5. Choose Layer > New Solid, type Right Eye for the name, set the size to 100 × 100 pixels, use the eyedropper to sample black for the color, and then click OK.

  6. Scroll down to the center of the composition, locate the new solid, and then drag the solid over the eye on the right.

  7. Open the Right Eye Layer window by double-clicking the solid. Drag the Layer window as close as you can to the Composition window.

  8. Make sure the Layer window is active, and click the oval tool in the toolbox.

  9. Use the oval tool to draw a mask in the center of the Layer window. The mask allows you to turn a rectangular solid into an oval-shaped solid.

    Once you create the initial shape, you can see the cat image beneath the solid in the Composition window. Use the Layer window to make adjustments to the mask. Don't worry about the exact size. The style of the illustration requires only a rough oval shape.
