rebounding particles move through each other.

View the animation again. This time, the
particles bounce off each other.
Tip: InterPart icle C ollisions, Deflector Binding,
and Bubble Noise do not get along well together.
Particles may leak through the deflector when
these three are used together. Instead of bubble
motion use animated mapping. Use facing
particles with an animated map of a bubble,
where the bubble is smaller than the map size.

Spray simulates water drops such as rain, a
fountain, the spray from a garden hose, and so on.
Kinds of Spray
Note: SuperSpray (page 2–245) is a more powerful
and advanced version of Spray. It provides all the
functionality of Spray, plus additional features.
Tip: To animate part icles following a path through
space, use the
Path Follow space warp (page 2–67) .
Procedure
To create spray:
1.
OntheCreatepanel,makesurethe
Geometry button is active and Particle Systems
is chosen in the objec t category list, then click
Spray.
2. Drag in a viewport to create the Spray emitter;
see
Creating a Particle Emitter (page 2–235) .
The emitter’s direct ion vector points in the
negative Z direction of the active construction
plane. For example, if you create the emitter
in the Top view port, the particles will move
downward in the Front and Left viewports.
