Apple Motion 4 - Manual (Page 890)

The text characters are swept around the screen in a vortex pattern. If the text characters
start to move off the screen, they collide with the edge of the screen.
Related Objects is the default setting in the Affect parameter of the Vortex behavior,
which means that all objects within the same group are affected. You can change this to
Specific Objects to select which layers are affected, or change it to All Objects.
Note: Remember that behaviors often contain parameters that specify how layers to
which the behavior is applied are affected. These controls greatly influence the result of
a behavior when it is applied to text. For example, if you have text on a circular path and
you apply a Spin behavior to the text, the text layer rotates as a whole around its anchor
point. To rotate the individual text characters, select the Affect Subobjects checkbox in
the Spin parameters.
Spin behavior applied to text on a path with
Affect Subobjects turned on (the individual text
characters spin) Spin behavior applied to text on a path with
Affect Subobjects turned off (the text layer as a
whole spins)

Using Behaviors to Animate Text in 3D
Although text has no inherent 3D parameters, a text layer can moved and rotated in 3D
space. Simulation behaviors can also influence text characters to move out of their X and
Y planes into Z space. The text must be a member of a 3D group to be pulled out of the
X and Y planes by a behavior. Additionally, text on an Open Spline path can be
manipulated in 3D space.
