the “Emission” tab, change the “Amount” value to 100 and the “Lifetime” value to 250. In the
properties window - “Scene” button - “Gravity” tab, untick “Gravity” (Figure 12.88). In the
properties window - “Object Modifiers” button, click “Add Modifier” (you will see that there
is already a particle system modifier applied) and select “Explode.” With your cursor in the 3D
window, press Alt + the A key to see the sphere fly apart (Figure 12.89).

12.5.3 Particle Instance Modifiers
The particle instance modifier allows you to duplicate an object and
position the duplicates to mimic the position and number of par-
ticles emitted from a particle system. It follows that in order to apply
the particle instance modifier to an object, you must have a second
object in the scene object with a particle system attached.
As always, an example is a good way to explain this type of ap-
plication. Before you begin, be familiar with particle systems as de-
scribed in Chapter 13. In a new scene, delete the default cube and
add a plane object. De-
select the plane and add
a UV sphere—both the
plane and the sphere will
be located at the center of
the world (Figure 12.90).
Go to the “Scene” button in the properties
window and untick “Gravity” (Figure 12.91).
This is done so that particles emitted from an ob-
ject will not be subject to a gravitational force.
