3. With the Super Spray icon selected, open the Modify panel, and in the Basic Parameters rollout,
set the Off Axis and Off Plane Spread values to 40.
4. In the Particle Generation rollout, keep the default Rate and Speed values, but set the Speed
Variation to 50 to alter the speed of the various particles. Set the Particle Size to 20.
5. In the Particle Type rollout, select the MetaParticles option, set the Tension value to 1, and make
sure that the Automatic Coarseness option is selected.
6. Open the Material Editor (by pressing the M key), and drag the Purple Soda material to the parti-
cle system icon.
Figure 41.9 shows a rendered image of the MetaParticles spilling from a soda can at frame 25.

Instanced Geometry
Using the Particle Type rollout, you can select an object to use as the particle. If the Instanced Geometry
option is selected as the particle type, you can select an object to use as the particle. To choose an object to
use as a particle, click the Pick Object button and then select an object from the viewport. If the Use
Subtree Also option is selected, then all child objects are also included.

Caution
Using complicated objects as particles can slow down a system and increase the rendering time. n
The Animation Offset Keying option determines how an animated object that is selected as the particle is
animated. The None option animates all objects the same, regardless of when they are born. The Birth
option starts the animation for each object when it is created, and the Random option offsets the timing
randomly based on the Frame Offset value. For example, if you have selected an animated bee that flaps its
wings as the particle, and you select None as the Animation Offset Keying option, all the bees flap their
