When you clone a layer, any changes you make to the clone will also alter the original, and vice versa. One example where the technique may be useful is for creating a character shadow on a wall. The character can be cloned and the clone used as a Shadow matte. Any changes you make to the character will also be made to the shadow.

LAYERS EXERCISE 2: DUPLICATING AND CLONING

In this scene we’ll animate a raindrop ripple and duplicate it a number of times for an effect of rain on a pond surface.

> 1. Create a new throwaway scene. > 2. In the Timeline, rename the default layer ripple and then select frame 1. > 3. Using drawing tools and colours of your choice, animate a fourdrawing sequence of some ripples growing outward from the centre and dissipating, as shown in Figure 3.41. > 4. Add exposure to each drawing so they’re on doubles/twos (see page 149).

> 5. Right-click the ripple layer’s name and choose Duplicate Selected Layers.

The duplicated layer is automatically named with ‘_1’ appended for you, but like any layer, you can rename it if you prefer. At this point, the layers should appear as shown in Figure 3.42.

> 6. In the Timeline, [Shift]-select the first four frames (two drawings) of the duplicated ripple.

> 7. Press [Ctrl/⌘ X] to cut them from the Timeline. The blank frames should still be selected.

> 8. Making sure the blank frames are still selected, on your keyboard, press [Z]. This pulls the remaining drawings back to frame 1, leaving a gap at the end.

NOTE The [Z] key function in the Timeline is known as Clear and Pull, which can also be accessed by right-clicking drawings or blank frames Exposure ­ Clear Exposure and Pull.

> 9. In the ripple_1 layer, select frame 5 and then press [Ctrl/⌘ V] to paste those frames you cut in Step 7, onto the end.

> 10. Move the playhead to frame 8 and click the Stop Frame label in the top toolbar.

> 11. Activate playback looping and press [Shift Enter] to watch the playback.

In this exercise you’ve created two ripples from one, in a fraction of the time it’d take to animate two. For rain on a pond surface, you could ­ fill the scene with these ripples, o setting each by a different number of frames.

In the next exercise I’ll set you on the path to do this yourself, where you’ll reposition all the drawings of your duplicated ripple layer.
