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.
Front Layer, Side Layer, Back Layer Specify the layer to be mapped onto the corresponding side of the piece. Front

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 for the Shatter effect
The Camera System control specifies whether to use Camera Position, Corner Pins, or Comp Camera. Comp
Camera tracks the composition's camera and light positions and renders a 3D image on the layer.
Camera Position controls specify the camera position:
X Rotation, Y Rotation, Z Rotation Rotate the camera around the corresponding axis. Use these controls to look at
the layer from the top, side, back, or any other angle.
X, Y Position Specifies where the camera is positioned in (x,y) space.
Z Position Specifieswherethecameraispositionedinzspace.Smallernumbersmovethecameraclosertothelayer,
and larger numbers move the camera away from the layer.
Focal Length Specifies the zoom factor and is like a camera’s zoom lens. Smaller numbers zoom the camera lens out,
and larger numbers zoom the camera lens in.
Transform Order Specifies the order in which the camera rotates around its three axes and whether the camera
rotates before or after it is positioned using the other Camera Position controls.
Corner Pins controls for the Shatter effect
Corner pinning is an alternative camera control system. Use it as an aid for compositing your layer into a scene.
Upper Left Corner, Upper Right Corner, Lower Left Corner, Lower Right Corner Specify the location of each of the
four corners of your layer.
Auto Focal Length Controls the perspective of the effect during the animation. When Auto Focal Length is off, the
focal length you specify is used to find a camera position and orientation that positions the corners of the layer at the
corner pins. If this isn’t possible, the layer is replaced by its outline, drawn between the pins. When Auto Focal Length
is on, the focal length required to match the corner points is used, if possible. If not, Focal Length interpolates the
correct value from nearby frames.
Focal Length Overrides the other settings if the results you’ve obtained aren’t what you need. If you set Focal Length
to something that doesn’t correspond to what the focal length would be if the pins were actually in that configuration,
the image may look odd (strangely sheared, for example). But if you know the focal length that you are trying to
match, Focal Length is the easiest way to get correct results.
