object using the Pick Object button in the Parameters rollout. Its Parameters rollout includes a Timing sec-
tion with Time On and Time Off values and a Reflection section.
The difference between this type of Space Warp and the DynaFlect Space Warp is the addition of refraction.
Particles bound to this Space Warp can be refracted through an object. The values entered in the Refraction
section of the Parameters rollout change the velocity and direction of a particle. The Refracts value is the
percentage of particles that are refracted. The Pass Vel (velocity) is the amount that the particle speed
changes when entering the object; a value of 100 maintains the same speed. The Distortion value affects the
angle of refraction; a value of 0 maintains the same angle, and a value of 100 causes the particle to move
along the surface of the struck object. The Diffusion value spreads the particles throughout the struck
object. You can vary each of these values by using its respective Variation value.
Note
If the Refracts value is set to 100 percent, no particles are available to be refracted. n
You can also specify Friction and Inherit Velocity values. In the Spawn Effects Only section, the Spawns
and Pass Velocity values control how many particle spawns are available and their velocity upon entering
the struck object. Figure 42.11 shows each of these Space Warps bound to a Super Spray particle system.
The Reflect percentage for each of the Space Warps is set to 50, and the remaining particles are refracted
through the Space Warp’s plane. Notice that the particles are also reflecting off the opposite side of the
refracting object.
