regulation between Conductivity State values. However, large
Conductivity State values cause extremely jumpy animation. Use
smaller values for standard lightning effects. A wiggle expression
with a small amplitude value would also work well here.
Even though Conductivity State is the standard way to animate
Advanced Lightning, you can also use other properties. If you
want to your lightning to move, you might not want to animate
much besides the Origin or Direction points. Movement of these
points will cause enough randomization to create animated light-
ning. Animating both direction points and Conductivity State can
create too much random movement in most cases.
3D Scratches
For these scratches,
I've reduced the
Turbulence value
to smooth out the lines
a little, as well as of the
Core Radius value in the
Core Settings area in the
Effect Controls panel. I've
also opened up the Glow
Settings area and removed
the glow by reducing the
Glow Radius value to 1.0
(its minimum value), and
raising the Glow Opacity
value to 0%. Because these
lines are so thin, they hold
up well when animated in
3D space.
Advanced Lightning as a Design Element
In the Advanced Lightning.aep project, you'll fi nd a composi-
tion called Design Element. This contains a couple of solid layers,
with the upper one containing some lightning from this effect,
and the bottom containing a simple texture. As I've been stress-
ing throughout this topic, it's important to be aware of alternative
uses of effects. Because Advanced Lightning doesn't animate on
its own, we can use it to create sketchy lines or cracks when cre-
ating grungy textures (Fig. 9.7).

Lightning effect, used as a design
element.
