Working with Particles
Render Order: A pop-up menu that determines whether new particles are drawn on
top of or underneath particles that have already been generated. There are two
options:
 Oldest First: New particles appear on top of older particles.
 Oldest Last: New particles appear underneath older particles.
Interleave Particles: Turning this checkbox on mixes particles generated from multiple
cells together. Turning this checkbox off layers particles in the same order as the cells
that generate them.
Note: This option has no effect with particle systems containing only one cell. Leaving
this option off speeds rendering with multiple cells.
Emitter 3D Checkbox
The 3D checkbox is located in the Emitter tab underneath the emitter-specific
parameters. When this control is turned on, the 3D emitter shapes (Box and Sphere)
become available. Because all emitter shapes can be used in 3D space, additional 3D
parameters are available for all emitter shapes when 3D is turned on. These additional
parameters appear in the Emitter Inspector and HUD.
These parameters are available for all shapes, regardless of the Arrangement setting.
For more information on the additional 3D controls in the HUD, see “

Turn on the 3D checkbox.

rendering methods for the particles.
