PDynaFlect Space Warp 79
Inter face
Timing group
The two spinners specify the start f rame and end
frame of the deflection effect.
Time On/Off—Time On specifies the frame at which
the deflection beg ins, and Time Off specifies the
frame at which the deflection ends.
Particle Bounce group
These settings affect the reflection of particles
from the space warp.
Reflects—Specifies the percentage of particles to
be reflected by the PDy naFlect.
This affects both the particles and the dynamics
reaction of the object struck by the particles. The
more particles that strike the affected object, the
more force applied to that object. If set to 0.0, the
particles have no effect on the object.
Bounce—This is a multiplier that specifies how
muchoftheinitialspeedoftheparticleis
maintained after collision with the PDynaFlect.
Using the default setting of 1.0 causes the particle
to rebound with the same speed as it collides. A
real-world effect would usually be less than 1.0.
For a "flubber" effect, set greater than 1.0.
Variation—Specifies the variation of Bounce
applied to the range of particles.
For example, a Variation setting of 50% applied to
a Bounce setting of 1.0 would result in randomly
applied Bounce values ranging from 0.5 to 1.5.
Chao s —Applies a random variation to the bounce
angle.
When you set Chaos to 0.0 (no chaos), a ll par ticles
bounce off the PDynaFlect surface perfectly (like
banking pool balls). A non-zero setting causes the
deflected particles to scatter.
Fr ict io n —The amount by which particles are
slowed as they move along the deflector surface.
Avalueof0%meansthey’renotslowedatall.A
value of 50% means they’re slowed to half their
original speed. A va lue of 100% means they stop
moving when they str ike the surface. Default=0%.
Range=0% to 100%.
Tip: To have pa rticles 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 str ike the surface at an angle other than 90
degrees.
Inherit Vel—(Velocity Inheritance) Determines
how much of a moving PDy naFlect’s speed is
applied to reflected or refracted p articles.
