72 Chapter 11: Space Warps and Particle Systems
Inter face Current Path group
Lets you choose the path for the particles, and
specify the range of influence of the Space Warp.
Object—Displaysthenameofthecurrently
assigned path.
Pick Shape Object—Click this, and then click a
shapeinthescenetoselectitasapath.Youcan
use any shape object as a path; if you select a
multiple-splineshape,onlyonethelowest-number
spline is used. You can also use NURBS curves as
paths.
Unlimited R ange—When off, the r ange of influence
of the space warp is limited to the val ue set
intheDistancespinner. Whenon,thespace
warp influences all bound particles in the scene,
regardless of their distance from the path object.
Range—Specifies the range of influence when
Unlimited Range is off. This is the distance
between t he path object and the particle system.
The position of the Path Follow space warp’s icon
is ignored.
Motion Timing group
These cont rols affect how long particles are
influenced by Path Follow.
Start Frame—TheframeatwhichPathFollow
begins to influence the particles.
Tra vel Time—Thetimeeachparticletakesto
traverse the path.
Variation—The amount by which each particle’s
travel time can vary.
Last Frame—TheframeatwhichPathFollow
releases the particles and no longer influences
them.
