Apple Motion 2 - Manual (Page 246)

246 Chapter 3 Basic Compositing
In cases where a stack of overlapping objects appears, each with a different blend
mode, the bottommost pair of objects is combined first, and that combination then
interacts with the next object up, and so on until all overlapping objects have been
combined for the final image. In this case, each object with a specified blend mode
only interacts with the image below it, whether that image is a single object or a pair
of objects that have been blended together.
Each of Motion’s blend modes works in conjunction with the Opacity parameter to
alter the interaction between the foreground and background objects. Adjusting an
object’s opacity lessens the blending effect that is assigned to it, even as it reduces that
object’s visibility. This allows you to customize any blend mode to better suit your
needs.
Blend modes only affect overlapping objects, and have no interaction with your
project’s background color. If you specify a blend mode for an object that doesn’t
overlap anything, that object remains as it was before.
To change a selected object’s blend mode, do one of the following:
m Choose an option from the Blend Mode pop-up menu in the Dashboard.
m Choose an option from the Blend Mode pop-up menu in the Properties tab.
m Choose Object > Blend Mode, then choose an option from the submenu.
m Display the Blend Mode column in the Layers tab, then choose an option from an
object’s Blend Mode pop-up menu.
m Control-click an object in the Canvas, then choose an option from the Blend Mode
submenu in the shortcut menu.
m Control-click an object in the Layers tab or Timeline Layer list, then choose an option
from the Blend Mode submenu in the shortcut menu.
