AFTER EFFECTS CS3 509
User Guide
Determines what happens to the pieces after they break up and blow apart. The higher the gravity setting,
Gravity
the faster the pieces are sucked in the direction set by Gravity Direction and Gravity Inclination.
Defines the direction in (x,y) space that the pieces travel when affected by gravity. The direction
Gravity Direction
is relative to the layer. If Gravity Inclination is set to -90 or 90, Gravity Direction has no effect.
Determines the direction in z space that the pieces travel once they explode. A value of 90
Gravity Inclination
explodes the pieces forward, relative to the layer. A value of -90 explodes them backward, relative to the layer.
Textures controls
Textures controls specify the texture of the pieces.
Specifies the color of the piece as defined by the Front Mode, Side Mode, and Back Mode menus. This color
Color
may or may not be visible depending on the Mode settings: When a Mode setting is Color, Tinted Layer, Color +
Opacity, or Tinted Layer + Opacity, the selected color is factored into the appearance of the piece.
Controls the opacity of the corresponding Mode setting. A Mode setting must be Color + Opacity, Layer +
Opacity
Opacity, or Tinted Layer + Opacity for the opacity to affect the appearance of the piece. You can use the Opacity
control in conjunction with texture maps to create the look of semitransparent materials.
Determine the appearance of the front, sides, and back of the pieces. Color
Front Mode, Side Mode, Back Mode
applies the selected color to the applicable side of the piece. Layer takes the layer chosen in the corresponding Layer
menu and maps it to the applicable side of the piece. Tinted Layer blends the chosen layer with the selected color;
the effect is similar to viewing the layer through a colored filter. Color + Opacity combines the selected color and the
Opacity amount. With Opacity at 1, the applicable side is given the selected color. With Opacity at 0, the applicable
side is transparent. Layer + Opacity combines the chosen layer and the Opacity amount. With Opacity at 1, the
chosen layer is mapped to the applicable side. With Opacity at 0, the applicable side is transparent. Tinted Layer +
Opacity combines the tinted chosen layer and the Opacity amount. With Opacity at 1, the tinted chosen layer is
mapped to the applicable side. With Opacity at 0, the applicable side is transparent.
Note: If you apply Shatter to a layer containing an alpha channel that you want to use for transparency, use the same
texture (or at least another layer with an identical alpha channel) for the front, sides, and back of the pieces to make all
sides transparent.
Specify the layer to be mapped onto the corresponding side of the piece. Front
Front Layer, Side Layer, Back Layer
Layer maps the chosen layer to the front of the piece. Back Layer maps the chosen layer backward to the layer. If Layer
is chosen for both Front Mode and Back Mode, and the same layer is specified for each, each shattered piece has the
same pixel information on both sides. Side Layer maps an extrusion of the chosen layer to the extruded sides of the
piece, as if the chosen layer is also mapped to the front and back, and the layer has been sliced through.
Note: If you choose a layer with an effect applied, the effect does not show up in the texture unless you precompose the
layer. However, if you select None, the layer to which you have applied Shatter, along with any effects that occur before
Shatter, is used as the texture map, with no precomposing required.
Camera System and Camera Position controls
Whether to use the effect's Camera Position properties, the effect's Corner Pins properties, or the
Camera System
default composition camera and light positions to render 3D images.
Rotate the camera around the corresponding axis. Use these controls to look at
X Rotation, Y Rotation, Z Rotation
the cards from the top, side, back, or any other angle.
Where the camera is positioned in (x,y) space.
X, Y Position
Where the camera is positioned along the z axis. Smaller numbers move the camera closer to the cards,
Z Position
and larger numbers move the camera away from the cards.
