Masks
You can apply masks to the image source of a particle cell. The effect of the mask on the
cell source is carried through to the emitted particles.
You can also apply masks to the emitter object itself.
For more information on working with masks, see Intro to masks and transparency in
Motion.
Save custom particle effects in Motion
After you create a particle system, you can save it as a particle preset in the Particle
Emitters, Favorites, or Favorites Menu folder in the Library, for future use. When you place
particle systems in the Library, they become particle presets that can be used like any
other particle preset.
Tip: For organizational purposes, create a folder of your own in the Favorites or
Favorites Menu category to store custom particle systems.
Save a particle system to the Library
1. In Motion, open the Library and select the Particle Emitters, Favorites, or Favorites
Menu category.
2. Drag the emitter you want to save from the Layers list into the stack at the bottom of
the Library.
The customized emitter is saved in the /Users/username/Library/Application Support/
Motion/Library/ folder (in the Particle Emitters, Favorites, or Favorites Menu subfolder).
Any custom layers created in Motion (such as a shape layer) that you used to create
that particle system are included in the file.
