Esc .
Remove—Removes hig hlighted space war ps from
the list.
(Li st)—Lists a ll spring space warps by name.
Calculation Parameters group
Start Frame—The frame at which the Spring
controller first ta kes effect. D efault=0.
Iterations—The accuracy of the controller
application. If you get un expected results, try
increasing this setting. Default=2. Range=0 to 4.
X/Y /Z Ef fect— These sett ings let you control the
percentage of the effect on the individual world
axes. Default=100. Range=0 to 200.

TCB Controllers produce curve-based animation
much lik e Bezier controllers. H owever, TCB
controllers do not use tangent types or adjustable
tangent h andles. They use fields to adjust the
Tension, Continuity, and Bias of the animation.

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 propert ies), you
can change the p a rameters in the Key Info dialog
and see the trajector y 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 rotat ions, you can
reassign it to be the default rotation controller.
Procedure
To change an Euler XYZ Rotation controller into a
TCB R otation controller:
1.
Select an object animated with an Euler XYZ
rotation controller .
2. In Motion panel > Parameters > Assign
Controller rollout, select the Rotation track in
the list window.
3. Click Assign Con troller, and then select
Quaternion (TCB).
You can also assign this controller in Track
View or from the Animation menu.
