Apple Motion 4 - Manual (Page 664)

If you want your particles to intersect with other rotated layers, choose In Global 3D
(Better) from the Render Particles pop-up menu in the Emitter Inspector. In the following
image on the left, Global 3D is selected so the particles intersect with other objects in
the project that are transformed in 3D space. In the image on the right, Local 3D is selected
so the particles do not intersect with other objects.
Saving Custom Particle Effects to the Library
Once you have created a particle system that you are particularly proud of, you can save
it as a particle preset in the Particle Emitters, Favorites, or Favorites Menu folder of the
Library, for future use. Once you place particle systems in the Library, they become particle
presets that can be used just like any other particle preset.
Note: For organizational purposes, you may find it useful to create a new folder of your
own in the Favorites or Favorites Menu category to store custom particle systems.
To save a particle system to the Library
1 Open the Library and select either the Particle Emitters, Favorites, or Favorites Menu
category.
2 Drag the emitter you want to save into the stack at the bottom of the Library.
When you save a particle preset, it’s saved as a file in the
/Users/username/Library/Application Support/Final Cut Studio/Motion/Library/Particle
Emitters/ folder. Any custom objects that you used to create that particle system also
appear here.
You can copy particle presets you create from this location to give to other Motion users,
or you can place particle presets that are given to you in this same folder. Whenever you
copy a particle preset file, you should make sure that you also copy any graphics or movie
files that it uses as well.
For more information on saving custom objects to the Library, see Adding Your Own
Content to the Library .
