Emitter G roup
The emitter specifies the area w here particles
appear in the scene. I t has a geometry you can
display in viewports, but it isn’t renderable.
The emitter is displayed as a rectangle with a
vector pointing out of one side. The vector shows
the direction in which the system emits particles.
You set emitter parameters in t he Emitter g roup of
theparticlesystem’sParametersrollout.
Width and Length—You implicitly set the initial
value of these parameters when you drag in a
viewport to create the emitter. You can adjust the
values in the rollout.
Thespaceoccupiedbytheparticlesystematany
given time is the result of a combination of its
initial parameters (size of the emitter, and speed
and variation of emission) and any space warps
that have been applied.
Hide—Turn on to hide the e mitter in view p orts.
When off, the emitter is displayed in viewp orts.
The e mitter is never rendered. Default=off.

Super Spray emits a controlled spray of particles.
This particle system is like the simple Spray
particle system with the added power provided by
all the newer particle systems.
Tip: To animate part icles following a path through
space, use the
Path Follow space warp (page 2–67) .
