Creating a custom particle effect

To customize the settings for your particle effect, click the Custom Particles tab

or the

Particle track:

Any settings that you applied under

Allow changes on the Particles page are

carried over to the

Custom page. You can further customize your effect using the

following:

• GFX File The pattern file for the effect that you selected on the Particles

page is displayed under

GFX File. If you want to select a different pattern,

click

Browse, and select a different .gfx file.

• General Settings

$ Progression Sets the progression of your particle effect, at any frame.

For example, you can set the progression to 50% at the first frame to make

your particle pattern start only at its mid-point.

$ Spread Determines the point at which the particles start to explode. The

higher the spread, the closer to the beginning of your clip the particles start

to explode. For example, a spread of 100 indicates that all particles start to

explode at the first frame of the clip, and a spread of 20 indicates that all

particles explode by the 80% point of the clip.

$ Speed Sets the speed at which the particles explode.
