• Stroke: Contains controls for modifying paint strokes. Use these controls to set stroke
color and brush scale, and to adjust opacity, spacing, width, and other parameters.
• Advanced: Contains controls that allow the dabs of a paint stroke to be animated
like particles.
• Geometry: Contains controls that allow you to change the shape type, to close or
open a shape, to smooth a shape, and to adjust the position of a shape’s control
points using value sliders. For more information on working with shapes, see Using
Shapes, Masks, and Paint Strokes.
• Emitter: Contains controls for modifying a particle emitter, including emitter shape,
space (2D or 3D), angle, and range. This pane also provides access to cell controls. For
emitters with multiple cells, these controls affect all cells. For more information on
using particles, see Working with Particles.
• Particle Cell: Contains controls for modifying particle cells. Particle cells can only be
selected in the Layers list or Timeline layers list. This pane contains controls for attributes
such as birth rate, speed, angle, and color.
• Replicator: Contains controls for modifying replicator attributes, including shape, space
(2D or 3D), pattern, size, and cell controls. For more information on using the replicator,
see Using the Replicator.
• Replicator Cell: Contains controls for modifying replicator cells. Replicator cells can only
be selected in the Layers list or Timeline layers list. This pane contains controls for
attributes such as angle, color, and scale.
• Generator: Displays the parameters and attributes of the selected generator, such as
the Center, Size, and Intensity parameters of a Lens Flare generator. The parameters
listed depend on the selected generator. For more information on generators, see
Working with Generators.
• Audio Track: Contains controls for adjusting an audio file selected in the Audio list of
the Project pane or in the Audio Timeline, including level, pan, and output bus. For
more information on working with audio, see Working with Audio.
• Master: Contains controls for adjusting a Master audio track selected in the Audio list
of the Project pane, including level, pan, and the output bus of audio tracks in the
project. For more information on working with audio, see Working with Audio.
Toolbar
The toolbar, located in the center of the Motion workspace, provides access to the tools
for manipulating objects in the Canvas, as well as controls for adding objects to a project.
There are tools that transform objects in 2D or 3D space; tools that create text, shapes,
and masks; buttons that add cameras, lights, and generators; pop-up menus that apply
filters and behaviors to objects; and buttons that create particle systems and replicators.
