Controlling Particle Animation
Next, you’ll add some control to the animated particles.
Control the animated particles:
1 Open the Rotation And Collision rollout. In the Spin Speed Controls
group, set Spin Time to 50.
This will give some rotation to the chunks.
2 Open the Object Motion Inheritance rollout and set Influence to 0.0.
This will keep the asteroid movement and rotation from influencing the
movement of the particles.
By default, the particle animation will begin on frame 0. Because the
asteroid doesn’t blow up until frame 10, you’ll have to adjust the timing
of the particle animation.
3 Right-click an open rollout in the first column. Choose Particle Generation
from the list.
The Particle Generation rollout is now displayed.
TIPThis right-click menu lets you navigate to a particular rollout quickly.
4 In the Particle Timing group, set Emit Start to 11 and Life to 90.
The particles don't appear until frame 11, and they persist until the last
frame of the animation.
5 Move the time slider or play the animation in the viewport to see the
effect.
Now the asteroid starts to break into pieces after reaching the center of
the viewport.
