where the particles no longer follow the path. There is also a Variation value to add some randomness to
the movement of the particles.
The Basic Parameters rollout also includes a Particle Motion section with two options for controlling how
the particles proceed down the path: Along Offset Splines and Along Parallel Splines. The first causes the
particles to move along splines that are offset from the original, and the second moves all particles from
their initial location along parallel path splines. The Constant Speed option makes all particles move at the
same speed.
Also in the Particle Motion section is the Stream Taper value. This value is the amount by which the parti-
cles move away from the path over time. Options include Converge, Diverge, or Both. Converging streams
move all particles closer to the path, and diverging streams do the opposite. The Stream value is the number
of spiral turns that the particles take along the path. This swirling motion can be Clockwise,
Counterclockwise, or Bidirectional. The Seed value determines the randomness of the stream settings.
Figure 42.7 shows a Path Follow Space Warp bound to a Super Spray particle system. A Helix shape has
been selected as the path.

Gravity
The Gravity Space Warp adds the effect of gravity to a scene. This causes objects to accelerate in the direc-
tion specified by the Gravity Space Warp, like the Wind Space Warp. The Parameters rollout includes
