[list] Shows the mesh objects used as targets. If more than three target objects
apply, a scroll bar appears at the right side of the list.
Add Click this button, and then select a mesh object in the scene to add it to
the list as a target.
By List Click this button, and then use the Select Target Objects dialog to add
one or more mesh objects to the list. The objects must already exist in the
scene, and the dialog shows only eligible objects.
Remove To remove a target object from the list, first highlight it and then
click this button. Any removed objects remain in the scene.
Sync By Choose the time frame to use when sending particles toward animated
objects when using Animated Shape or Follow Target Animation:
■ Absolute Time Animation derived from the target is applied to particles
immediately.
■ Particle Age Animation derived from the target is applied to particles at
the corresponding frames of each particle's existence.
■ Event Duration Animation derived from the target is applied to particles
is applied to each particle starting when it first enters the event.
Animated Shape Turn on to allow particles to target the surface of an object
whose form is animated by scaling, by morphing, or with modifiers. This
requires more computation, because the destination must be updated at every
integration step.
Follow Target Animation Turn on to allow particles to follow a moving
target; that is, a target whose location is animated. This requires more
computation, because the destination must be updated at every integration
step.
Point Lets you specify where on its target a particle should land.
■ Random Each particle targets a random point on the target.
■ Closest Surface Each particle targets the nearest point of the target’s
surface.
■ By Script Vector The target point or points are defined using a Script
operator that defines values in the particleVector channel. The Script
operator can be anywhere upstream of the Find Target test.
