Apple Motion 4 - Manual (Page 1224)

• Filters are applied to the group in view space. In other words, the filter affects the group
as if it was applied to the lens of the camera viewing the group.

• Its children are lit individually.
• Only a 3D group with the Flatten parameter enabled has the Crop, Drop Shadow, and
Four Corner parameters.
Working with Objects Inside 2D Groups and Flattened 3D Groups
You can use the Isolate command to align the active view with the axis of a 2D group
or flattened 3D group. Doing so facilitates making adjustments to objects inside the
group. For more information on the Isolate command, see
Isolate .
Should you be unable to find an object in your project, you can locate it by resetting
its Position parameter to 0, 0, 0. This centers the object in the flat group.
When moving an object along its Z axis inside a flat group—which includes 2D groups
and flattened 3D groups—the object appears to grow larger or smaller rather than
move closer to or further away from the camera.
Lighting
Lighting can be applied to a motion graphics project to enhance the depth and scope
of compositions, or it can help in creating realistic environments for composites.
Motion’s lighting system only works on 3D groups and their children.
To add a light to a project
µ
Choose Object > New Light (or press Command-Shift-L).
A light object is added to the Layers tab, the Timeline, and the Canvas (represented there
by a wireframe icon), and the 3D transform tool in the Toolbar becomes active.
