Variation—
The amount by which each particle can
vary from the Bounce setting.

0.0). 100% induces a variation in reflection angle
of up to 90 degrees.
Fr iction —The amount by which par t icles are
slowed as they move a long the deflector surface.
Avalueof0%meansthey’renotslowedatall.A
value of 50% means they’re slowed to half their
original speed. A value of 100% means they stop
moving when they strike the surface. Default=0%.
Range=0% to 100%.
Tip: To have particles slide along a deflector surface,
set Bounce to 0. Also, unless influenced by a force
such as Wind or Gravity, particles meant to slide
should strike the surface at an ang le other than 90
degrees.
Inher it V el—(Velocity Inheritance) When grea ter
than 0, the motion of the deflector affects particles
as well as the other settings. For example, to
animate the SDeflector passing through a passive
array of particles, turn up this value to affect the
particles.

Two streams of particles striking two deflectors
The Deflector space warp acts as a planar shield to
repel the par ticles generated by a par ticle system.
For example, you can use Deflector to simulate
pavement being struck by rain. You can combine a
Deflector space warp with a Gravity space warp to
produce waterfal l and fount ain effects.

Procedure
To create a deflector:
1.
On the Create pane
l, click Space
Warp s. Choose Deflectors from the list, then
on the Object Type rollout, click Deflector.
2. Drag in a viewport to define the deflection area.
