11 On the Mapping rollout in Particle View, turn on Show Map In Viewport.
12
Go to frame 100 and turn on Auto Key.
13 On the Mapping rollout in Particle View, set Map Values > U=1.0.
14 For Sync By, choose Particle Age.
15
Turn off Auto Key, and click Play Animation.
As each particle is born and falls, its U mapping coordinate gradually
changes from 0.0 to 1.0, while its color changes to match the
corresponding position across the Gradient Ramp map.
To vary the effect, try changing the Gradient Type setting, and animate
the V and W values as well. Or, for more sophisticated effects, assign
animation controllers such as Noise Float to the Mapping coordinate
values, or wire them to other changing parameters in the scene
(Animation menu > Wire Parameters > Parameter Wire Dialog).
TIP In the Material Editor, it's easier to see the result of the Gradient Type
choice if you set Sample Type to Cube.
Interface
The user interface appears in the parameters panel, on the right side of the
Particle View dialog.
