Animation Offset Keying group
These controls are available only when Animated Shape is on.
Sync By Lets you choose how to synchronize reference-object animation with
the particles.
■ Absolute Time All particles have the same shape at any given moment.
■ Particle Age Animation of the reference object is synchronized with
particle age: Frame 0 of the reference-object animation corresponds to the
frame of each particle's birth.
■ Event Duration Frame 0 of the reference-object animation corresponds
to the moment the particle enters the event.
Rand Offset When on, randomly varies the start of each particle's animation.
Use the numeric setting to specify the number of frames by which the
animation start can vary.
Update Particle Shape Refreshes instanced particle shapes from the reference
object. Use this after changing an object in a hierarchical reference object.
In most cases, Particle Flow automatically updates instanced particles when
changes are made to the reference object. However, in some cases, when you
change an object deep in a hierarchy, the particle instances might not be
updated. In such a case, click Update Particle Shape to refresh the instances.
Uniqueness group
The Uniqueness setting enables changing the randomization of the scale
variation, animation offset, and the multi-shape random order.
Seed Specifies a randomization value.
New Calculates a new seed using a randomization formula.
Shape Mark Operator
Particle View on page 2811 > Click Shape Mark in an event or add a Shape Mark
operator to the particle system and then select it.
Use the Shape Mark operator to replace each particle with either a rectangle
or a box cut out from the particle geometry with an image mapped onto it.
The image can be animated and the animation can be synchronized with
particle events.
