Remove Highlight a deflector in the list, and then click this button to remove
it from the list. Any removed space warps remain in the scene.
Spawn Rate And Amount group
Use these settings to specify when particles are to spawn and other values
related to how many particles are spawned.
Spawn On First Collision Particles spawn only the first time they collide with
a deflector.
Delete Parent When on, deletes each original particle from which a new one
is spawned. Available only with the Spawn On First Collision option.
Spawn On Each Collision Particles spawn on each of multiple collisions, up
to a limit specified with the Until # parameter.
Until # The maximum number of collisions by the parent particles that
produce spawned particles. Available only with the Spawn On Each Collision
option. Default=3.
When Test True For > Parent Particles is on, parent particles test True only
after colliding the number of times specified by the Until # value.
Spawnable The percentage of particles in the current event that will spawn
new particles. This is determined once for each particle, when it enters the
event. However, the parameter is animatable. Default=100.0.
For values other than 100.0, Spawnable uses a randomized selection process,
which is affected by the Uniqueness Seed value. For example, with five parent
particles, Offspring #=1, and Spawnable=80.0, you might get any number of
spawned particles between two and five for each collision. The average per
spawning would be four, however.
Offspring # The number of new particles the system creates from each parent
particle for each spawning event. Default=1.
Variation The amount by which the Offspring # value can vary randomly.
Default=0.0.
To obtain the actual test value for each particle, the system multiplies the
Variation value by a random number between -1.0 and 1.0, and then applies
the result as a percentage of the Offspring # setting. For example, if Offspring
#=20 and Variation=10, then the actual number of offspring for each particle
would be between 18 and 22.
