Choosing Layer Map options (PB only)
After you have created default particles, use the Layer Map to replace dots with a particle source layer.
To replace default particles with a layer: - If necessary, import the source footage and add it to the composition.
- In the Timeline window, click the layer's eye icon (
) to hide it. - In the Effect Controls window under Particle Playground, expand the Layer Map property.
- For Use Layer, select a layer from the menu. The menu lists all layers used in the composition.
- For Time Offset Type, specify how you want particles to take frames from times other than the current time. This option applies only when you are mapping particles to a multiframe layer, such as a movie or a composition. For more information, see Specifying the frames you want to map (PB only).
- For Time Offset (or Random Time Max), specify a value. This option applies only if you are mapping particles to a multiframe layer.
Note: The name of this option changes from Time Offset to Random Time Max when you select either Relative Random or Absolute Random from the Time Offset Type menu. - To replace only some of the default particles with the mapped layer, specify the Affects options as necessary (see Using Affects options to specify particles (PB only)).
To stop using a mapped layer: In the Effect Controls window, under Particle Playground, expand the Layer Map property and choose None from the Use Layer menu.
