in moving toward the target. You can also specify where on the target the
particles should go.
Alternatively, you can use Find Target as a simple proximity test: If a particle
comes within a certain distance of its target, it becomes eligible for redirection
to the next event.
Find Target icon
When you add a Find Target test to the particle system in
Particle View on
page 2811, a spherical Find Target icon appears in the scene at the world origin
(0,0,0). You can use this icon as a target, or you can use one or more mesh
objects in the scene as targets. To display the Find Target parameters on the
Modify panel, select the icon. If you delete the icon, the software also deletes
the test.
NOTE If you add Find Target from the Create panel, Particle Flow creates a separate
event for the test in the particle diagram.
TIP In a particle loop, all particles end up at their respective starting positions,
enabling seamless repetition of the resulting animation. You can make particle
loops with Particle Flow using a Script operator and a Find Target operator. At the
start of the loop, the Script operator should read all particle positions and write
them into the MXS Vector channel. Then, at the end of the loop, set the Find
Target operator to Control by Time, set Timing to Absolute Time, set Time to the
end of the loop, and in the Target group, set Point to By Script Vector. Particle
Flow will direct particles to the previously cached position at the specified frame.
