TCB Controllers produce curve-based animation much like Bezier controllers.
However, TCB controllers do not use tangent types or adjustable tangent
handles. They use fields to adjust the Tension, Continuity, and Bias of the
animation.
This controller works well as a Position controller in conjunction with the
Motion panel > Trajectories display of an object. With sub-object keys turned
on and the Key Info dialog for a key displayed (right-click and select Key Info
on the selected key to display Key Info properties), you can change the
parameters in the Key Info dialog and see the trajectory path change. This
allows for very precise control of an object's trajectory with visual feedback.
Euler XYZ is now the default rotation controller in 3ds Max. The TCB Rotation
controller was the default rotation controller for files created in versions 4
and earlier.
TIP Euler XYZ behaves very differently than TCB rotations. Users upgrading from
versions 4 or earlier might have difficulty adapting to the differences between
these controllers. If you are used to working with TCB rotations, you can reassign
it to be the default rotation controller.
