The Follow/Bank utility
applies rotation keys to an object that already has a motion trajectory.
The settings are similar to those found in the Path constraint.
Use this when you have an object for which you've already assigned
motion and want it to follow or bank along its trajectory, but don’t
want to use a Path constraint.
changes the roll of a camera as it follows a path.
The utility aligns the
object's X axis to the direction of motion. To change the orientation,
change the pivot orientation in the Hierarchy Pivot
panel before using this utility.
Although many of the
settings are the same as in the Path constraint, this utility is
not dynamic; you have to click the Apply Follow button each time
you change an object's animation or the utility settings. When adjusting
banking settings, move to the point at which the object is at the sharpest
turn, then alternately click Apply Follow and adjust the banking
settings to get the right affect at the extreme corner.
TipYou can also use
an Orientation Constraint to manually control the rotation of the
object as it moves through space. While this is not automatic, it allows
more fine control on individual frames than other methods.
To apply the Follow/Bank utility:
- On the Utilities
panel, click the More button, and choose Follow/Bank from the list.
- Adjust the options in the Follow/Bank
the objects you want to follow/bank.
- Click the Apply Follow button.
The objects orient themselves
at the start frame, and follow or bank along their trajectories.

Apply Follow button
- Apply Follow
Applies the settings
and generates rotation keys. Each time you click this button, rotation
keys in the specified range of frames (set in the Samples group)
are deleted and regenerated.
Follow Options group
Contains the parameters
that specify whether or not to use banking, and the banking settings.
Turn on to cause the objects
to bank as well as follow the trajectory.
- Bank Amount
Adjusts the amount of the
banking to one side or the other, depending on whether the value
is positive or negative.
Controls how rapidly
the roll angle changes as an object moves through bends in the trajectory.
Smaller values make an object more responsive to subtle changes
in the curve while larger values minimize jerkiness.
- Allow Upside Down
Avoids the situation where
an object flips when going around a vertically oriented path.
Specifies the range of
frames over which rotation keys are generated, and the number of
keys to be generated.
Specifies the first frame rotation
keys are generated.
Specifies the last frame rotation
keys are generated.
Specifies the number
of rotation keys to be generated in the specified range.
