Using Generators as Particle Cell Sources
Like other objects, generators can be used as a source for particle cells. The following
example uses the Soft Gradient generator. It is recommended that you scale the
generator down in the Generator tab of the Inspector to give your particle system
more flexibility and to keep the project from taking too much processing power.
To use a generator as a particle cell source:
1 Add the Soft Gradient generator to your project.
2 In the HUD or Generator tab of the Inspector, lower the Radius value. This example uses
a Radius value of 40.
3 Lower the Width and Height values. In this example, Width is set to 82 and Height is
set to 75.
