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
After you create a particle system, you can save it as a particle preset in the Particle
Emitters, Favorites, or Favorites Menu folder of 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.
Note: For organizational purposes, create a 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 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/Motion/Library/ folder (in the Particle
Emitters or Favorites subfolder). 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 given to you in this same folder. When you copy a particle
preset file, 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 Content to
the Library.
