rather than the lifespan specified for the original particles in the Life spinner
on the
Particle Generation rollout on page 3049.
List window Displays a list of lifespan values. The first value on the list is
used for the first generation of spawned particles, the next value is used for
the next generation, and so on. If there are fewer values on the list than there
are spawnings, then the last value is used repeatedly for all remaining
spawnings.
Add Adds the value in the Lifespan spinner to the list window.
Delete Deletes the currently highlighted value in the list window.
Replace Lets you replace a value in the queue with a value in the Lifespan
spinner. To use, first place a new value in the Lifespan spinner, then select
the value in the queue you want to replace, and click the Replace button.
Lifespan Use this to set a value, and then click the Add button to add the
value to the list window.
Object Mutation Queue group
The options in this group let you switch between instanced-object particles
with each spawning (as set with the Spawns spinner). These options are
available only if Instanced Geometry is the current particle type.
List window Displays a list of objects to be instanced as particles. The first
object on the list is used for the first spawning, the second for the second
spawning, and so on. If there are fewer objects on the list than there are
spawnings, then the last object on the list is used for all remaining spawnings.
Pick Click this, and then select an object in the viewport to add to the list.
Note that the type of object you use is based on the settings in the Instancing
Parameters group of the Particle Type rollout. For example, if you've turned
on Subtree in that group, you can pick object hierarchies. Likewise, if you've
picked a group, you can use groups as your spawned particles.
Delete Deletes the currently highlighted object in the list window.
Replace Replaces an object in the queue with a different object. Select an
object in the queue to enable the Replace button. Click Replace, and then pick
an object in the scene to replace the highlighted item in the queue.
