Time On/Off Time On specifies the frame at which the deflection begins,
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 PDynaFlect.
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 much of the initial speed of
the particle is 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.
Chaos Applies a random variation to the bounce angle.
When you set Chaos to 0.0 (no chaos), all particles bounce off the PDynaFlect
surface perfectly (like banking pool balls). A non-zero setting causes the
deflected particles to scatter.
Friction The amount by which particles are slowed as they move along the
deflector surface. A value of 0% means they're not slowed at all. 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 angle other than 90 degrees.
Inherit Vel (Velocity Inheritance) Determines how much of a moving
PDynaFlect’s speed is applied to reflected or refracted particles.
For example, if Inherit Vel is 1.0, particles with no motion that are hit by a
moving PDynaFlect inherit the speed of the PDynaFlect at the point of
collision.
