Apple Motion 4 - Manual (Page 689)

While the duration of the source layers has no affect on the replicator, the duration of
each cell affects how long the elements created from that cell are visible in the project.
You can change a cell’s duration by dragging either its position or its In and Out points
in the Timeline. In this way, you can adjust the timing that defines when each cell type
appears. For example, to create a pattern in which three different types of elements
appear at different times in the animation, you could offset the cells in the Timeline. In
the following image, the arc cells appear first. One second later, the star cells appear. One
second after that, the circle cells appear.
Note: You can animate the opacity of each cell so that it fades in; you do this by keyframing
the Opacity parameter in the Replicator tab or the Replicator Cell tab.
For more information on adjusting the timing of layers in the Timeline, see Using the
Timeline .
Using the Replicator Onscreen Controls
In addition to using the Position parameters in the Properties tab or the Select/Transform
tool to move the replicator in the Canvas, you can also use the Adjust Item tool, one of
the 2D transform tools available in the Toolbar. This section provides two examples of
using the Adjust Item tool to modify a replicator.
To use the Adjust Item tool
1 Select the replicator you want to adjust.
