a portion of the particle system, only that part of
the system is affected.
If you turn on Range Indicator (see following), t he
extent of the range is indicated by a tri-hooped
sphere. If you choose Unlimited Range, this
parameter has no effect.

Particles following a spiral path
The Path Follow space warp forces part icles to
follow a spline path.
Pr ocedur es
To create a Path Follow space warp:
1.
On the Create p anel, click Space
War ps. Choose Forces from the list, t hen on the
Object Type rollout, click Path Follow.
2. Click and drag in a viewport to define the size.
The Pat h Follow warp appears as a box-shaped
icon cont aining curved lines that indicate
hypothetical paths.
To set up and use Path Follow:
1.
Create a shape consisting of a single spline.
(You can use shapes with multiple splines, but
the s of tware uses only one spline for the p ath.)
2. Create a particle system and set its parameters
to emit particles over a range of frames.
3. OntheCreatepanel,clickPathFollow,and
draginaviewporttocreatethePathFollow
icon (a cube with wavy lines). The display and
position of this icon don’t affect the particles.
4. On the Basic Parameters rollout, click Pick
ShapeObjectandselectthesplineyoucreated
earlier.
5. Bind the Path Follow icon to the particle
system.
6. Adjust the Path Follow parameters to create the
particle movement you want.
Note: You can f u rther animate the particle effect
by animating the spline vertices.
Tip: To adjust the position of the path or particle
system while maintaining access to the Path
Followparameters,turnonModifierStack
rollout > Pin Stack while the Path Follow space
warp is selected.
If the particles don’t follow the emitter after it’s
moved, then change any PathFollow p arameter,
and t he motion will be corrected.
