default, the fl ip axis is the X-axis, meaning that the cards rotate
around the X-axis when transitioning. You can also set Flip Axis
to Y, which makes the cards fl ip around the Y axis when transi-
tioning. Note that the cards can still transition from left to right
(or any other order you choose from the Flip Order drop down),
but the cards themselves will spin on their own individual Y-axis.
But the Flip Axis drop down also allows you to select Random,
which causes each card to randomly fl ip along the X- or Y-axis.
The results are actually quite chaotic and artistic. You can also
have more control over how your cards fl ip by using a gradient
layer to control the fl ip order. To do this, select Gradient from the
Flip Order drop down and then choose the gradient layer from
the Gradient Layer drop down. Note that if you create the gradi-
ent using effects, layer styles, or shape layers that you might have
to precompose the layer before it can be used as a map for effects
(Fig. 20.9 ).

card randomly fl ips around it's
own X- or Y-axis.
Like many effects we've already discussed, this effect operates
in 3D space. There are camera controls, as well as lighting and
material options. And as with Shatter, and other such 3D effects,
you can animate the camera built into the effect, animate the
perspective using Corner Pins, or control the 3D movement with
a camera in the composition. Choose your method of movement
from the Camera System drop down.
The last two properties are perhaps the most special of the fea-
tures in Card Wipe. You might have noticed that Card Wipe does
not autoanimate. However, if you do want to add some random
animation to these cards, the developers of Card Wipe have
made it so that you don't have to even set keyframes (or use
