The user interface appears in the parameters panel, on the right side of the
Particle View dialog.
In the context of Collision Spawn, a parent is the original particle from which
new particles are spawned.
Test True for group
These check boxes let you specify which particles, if any, should become
eligible for redirection to the next event upon satisfaction of the test
conditions.
NOTE After a particle tests True, the Collision Spawn test no longer tests the
particle for collision. If you simply want particles to spawn every time they collide,
turn either or both of these off and use a different test for redirection.
Parent Particles When on, parent particles qualify for redirection when the
test conditions are met. Default=on.
When using the
Spawn On First Collision option on page 2968, Parent Particles
is available only when Delete Parent is off.
This option is also available when using the Spawn On Each Collision option
on page 2968. In this case, parent particles test True only after colliding the
number of times specified by the Until # value.
Spawn Particles When on, spawned particles qualify for redirection when
the test conditions are met. Default=on.
Deflectors group
This group displays the deflectors currently in effect, and let you add and
remove deflectors.
[list] Shows the deflectors that apply to this operator. If more than three
deflectors apply, a scroll bar appears at the right side of the list.
If you delete a listed space warp from the scene, its name is replaced in the
list by the entry “<deleted>”.
Add Click this button, and then select a Deflector space warp in the scene to
add it to the list.
By List Click this button, and then use the Select Deflectors dialog to add one
or more space warps to the list. The space warps must already exist in the
scene.
