Show Objects
If this option is disabled, the particles will be displayed in the viewport as lines. The direction and
length of each line indicates the direction of ight and current speed of the respective particle — the
longer the line, the faster the particle. If this option is enabled, the particles will be displayed in the
viewport as objects (provided you’ve made an object a child of the emitter). This display mode can
slow down the redraw rate considerably, especially when using complex objects as particles.
Emitter Tab
Emitter Type
Choose whether the particles will be emitted in the shape of a cone or pyramid.
X-Size, Y-Size
Give the size of the emitter. You can also scale the emitter by selecting the Scale tool and dragging
in the viewport.
Angle Horizontal, Angle Vertical
These parameters set the value of the emission angle. If Emitter Type is set to Cone, the horizontal
range is from 0° to 90°; with the Emitter Type set to Pyramid, the horizontal range is from 0° to 360°
and the vertical range is from 0° to 180°.
For example, to create a radial emitter, set Emitter Type to Pyramid, set X-Size and Y-Size both to 0,
Angle Horizontal to 360° and Angle Vertical to 0°.
