part icles produced in the viewpor ts and when
rendering.
Emitter Icon group
Logo S i ze —Sets the size of the Particle Flow logo,
which appears at the center of the source icon,
as well as the arrow that indicates the default
direction of particle motion.
By default, the logo size is proportional to that of
the source icon; with t his control, you can ma ke
it larger or smaller.
This setting affects only the viewport display of
the logo; changing it has no effect on the particle
system.
Icon Type—Choo se the basic geometry of the
sourceicon:Rectangle,Box,Circle,orSphere.
Default=Rectangle.
This choice matters only if you use the source icon
astheparticleemitter.Theavailablesizesettings
depend on which icon type you choose, and,
again, are important only if you use the source
icon as an emitter.
The default icon type is Rectangle. If you add a
particle system, and then change the icon typ e to
Box, the icon continues to resemble a rectangle. To
make it look like a box, increase the Height setting.
Lengt h/Dia met er —Sets the length of the Rectangle
and Box icon ty pes, and the diameter of the Circle
and Sphere icon t yp es.
Width—Sets the width of the Rectangle and Box
icon types. Unavailable with the Circle and Sphere
icon types.
Height—Sets the height of the Box icon type.
Available only with the Box icon type.
Show Logo/Icon—Turns display of the logo (w ith
arrow)andicononandoff,respectively.
These settings affect only the viewport display of
these items; they have no effect on the particle
system.
Quantit y Multiplier group
These settings determine the percentage of the
total number of part icles in each
flow (page
3–1036)
that are actually produced in the
viewports and at render time. They don’t affect the
percentage of particles that are visible; those are
determined by the
Display operator (page 2–198)
and Render operator (p age 2–202) .Youcanuse
them to quickly decrease or increase the number of
particles consistently throughout all events in the
particle system. The maximum setting, 10,000%,
lets you multiply the number of particles generated
by the flow by 100.
Thetotalnumberofparticlesisdeterminedby
the combined effects of the following operators
and tests:
Birth (page 2–139) , Birth Script (page
2–141)
, Delete (page 2–142) , Collision Spawn
(page 2–211)
,and Spawn (page 2–226) .Scripted
operatorsandtestscanalsoaffectthisnumber.
Viewport—Sets the p ercentage of the total
number of particles in the system produced in the
viewports. Default=50.0. Range=0.0 to 10000.0.
Render—Sets the percentage of the total number of
particles in the system produced at render time.
Default=100.0. Range=0.0 to 10000.0.
