Controls in the Shapes Tab
The Shapes tab has the following controls:
 Current Secondary: Lists which of the eight available tabs in the Secondaries room is
the currently selected secondary operation. When you click the Attach button, this is
the secondary tab that the currently selected shape will be attached to.
 Attached Shape: When you select a shape that has been attached to a shot’s
secondary tab, this field shows the selected shape’s name, and the grade to which it’s
been attached using the following format: shapeName.gradeNumber
 Attach button: Once you’ve drawn a shape you want to use to limit a secondary
operation, click Attach to attach it to the currently open secondary tab in the
Secondaries room (shown in the Current Secondary field).
 Detach button: Click Detach to break the relationship of a shape to the secondary
tab to which it was previously assigned. Once detached, a shape no longer has a
limiting effect on a secondary operation.
 Shapes List: This list shows all the unattached shapes that are available in a project,
as well as the shapes that have been assigned to the current shot. This list is covered
in more detail below.
 Hide Shape Handles: Click Hide Shape Handles to hide the control points of shapes in
the Image Preview. The outline of the shape remains visible.
 Reverse Normals: When a shape is feathered using the Softness parameter, this
button reverses which shape defines the inner and outer edges of feathering.
 Use Tracker: If you’ve analyzed one or more motion trackers in the current project,
you can specify which tracker, by number, to use to automatically animate the
position of the current shape. To disassociate a shape from the tracker’s influence, set
this value to 0.
 Softness: A global feathering operation for the entire shape. When set to 0, the shape
has a hard (but antialiased) edge. When set to any value above 0, inner and outer
softness shapes appear along with their own control points. The inner shape shows
where the feathering begins, while the outer shape shows the very edge of the
feathered shape. If necessary, each border can be independently adjusted.
 Shape Name: This field defaults to “untitled”; however, you can enter your own name
for the currently selected shape in order to better organize the shots list.
 New: Click New to create a new, unassigned shape.
 Remove: Choose a shape and click Remove to delete a shape from the shapes list.
 Close Shape/Open Shape: This button toggles the currently selected shape between a
closed and open state.
 Save button: Saves the currently selected shape to the shape favorites directory.
 Load button: Loads all shapes that are currently saved in the shape favorites
directory into the shapes list of the current shot.
