This is used for bone dynamics especially.
You??™ll see this in full action later in the dynamics chapters of this book.
Move TCBTool
The Move TCB command is sort of a new incarnation of an old feature.When you create
a motion path with an object, LightWave creates a curve. Tension, Continuity, and Bias
(TCB) are settings you can adjust for each keyframe on a motion curve.A common application
is to set a positive tension for the keyframe at the end of a motion, to make the
moving object ???ease into??? place. If this has always been possible in LightWave, then what??™s
the big deal about the Move TCB button? Up until now, you had to open the Graph Editor,
select the specific channel(s) to edit, and apply the appropriate T, C, or B settings. Now,
you can use the Move TCB tool directly in Layout. You can see your settings down at the
bottom left of the Layout interface in the Info area. All you need to do is press Ctrl+g for
the selected item to activate, then click and drag in the Layout to set Tension, hold Ctrl and
drag to set Continuity, then right-click for Bias.
Sliders
The Sliders tool lets you attach slider controls to items in your scene for specific control
over their behaviors.
