Layers Tab
The Layers tab of the Project pane provides an overview of all the layers, effects, and
masks currently used in your project. The hierarchy of items in the list illustrates which
objects are above or below other objects in the Canvas. All objects, with the exception
of cameras and lights, must reside within groups. Masks, behaviors, and effects can be
applied to groups or to individual layers. Applied masks, behaviors, and effects are
listed beneath the group or layer to which they are applied. The masks, behaviors, and
effects appear indented in the list.
The Name and Status columns in the Layers list display several icons that indicate
linked audio, 2D/3D status, or lock status. By default, applied masks, behaviors, and
filters also appear in the Layers list. You can turn the display of these objects on or off in
the Layers tab.
To display the Layers tab, do one of the following:
m Click the Project icon in the Toolbar.
m Choose Window > Layers.
m Press Command-4.
m If the Project pane is already visible, click the Layers tab at the top of the pane.
