spray (based on the orientation of the emitter
icon and indicated by the icon arrow) depends
on the viewport in which you create the icon.
Generally, the particles spray toward you when
created in an orthographic viewport, or spray
upward when created in a Perspective viewport.
3. Adjust the various parameters to alter the spray
effect.

These items control the direction and spread of
particles.
Off Axis—Affects the angle of the par ticle stream
off the Z axis (along the plane of the X axis).
Spread—Affects the spread of the particles away
from the emission vector (along the plane of the
X axis).
Off Plane—Affects the angle of emission about the
Z a xis. This has no effect if Off Axis is set to 0.
Spread—Affects the spread of the particles about
the Off Plane axis. This has no effect if Off Axis
is set to 0.
