So why even use keyframes? Timing, my friend. Timing. To create an animation that??™s
really ???in the pocket,??? you need to master the art of timing. That??™s right, the art of timing.
It is an art, and you??™ve either got it or you don??™t. Not to sound harsh, but timing is everything
??”in life, in comedy, and in animation. In 3D animation, you control timing with
keyframes. The more often you work with keyframes, the more quickly you will get a feel
for animation timing.
An expression is a LightWave function that lets you to set specific operations based on
mathematical statements. For example, you can select an animated wheel object, and
create an expression that tells Layout,???When the wheel rotates a full 360 degrees,
turn on a light and rotate another object.??? Expressions are very powerful and one of
LightWave??™s most advanced features.

Keyframing is the act of setting or marking an animatable attribute in time. For example,
when you want a ball to move from point A to point B over two seconds, you need to set
a keyframe at point A to tell LightWave to ???start here??? at point A in time, and another
keyframe, two seconds later in the timeline at point B, to say ???end here.
