Another example of how you might make use of the object/layer hierarchy can be seen
through the application of filters and behaviors. If you apply a filter to a single object
within a layer, it affects only that object. All other objects within the layer remain
unaffected.
However, If you apply the same filter directly to the layer, all objects that are nested
within that layer are affected by the filter, as if they were a single object.
The Background of Your Project
Two parameters in the Project Properties dialog affect the background color, and how
it appears when it’s exported out of Motion.
Background Color: The color that appears in the Canvas if no other graphic or
QuickTime object is present. If the Background Opacity is set to 0 percent and you
export your project with a premultiplied alpha channel, the color you select here is the
color the alpha channel is premultiplied with.
