sort of particle effect, as well as to fi re and “magic spar-
kle” effects, lies almost entirely in the materials. The
basic motion of the particle system is simple: a small
emitter object with
Normal
velocity activated, a slight
positive
AccZ
force value so that the smoke rises, and a
bit of
Brownian
motion to give it some swirl. A typi-
cal confi guration can be found in Figure 14.39.
The particle's native material mode is called a
Halo
, and
a setup for making smoke is shown in Figure 14.40.
The deviation from the default settings that are neces-
sary to achieve a smoke effect are:
