Animation menu Constraints Orientation
An Orientation constraint
causes an object’s orientation to follow the orientation of an object
or averaged orientation of several objects.

An Orientation Constrained
object can be any rotatable object. When constrained it will inherit
its rotation from a target object. Once constrained you can not
rotate the object manually. You may move or scale the object as
long as its not constrained in a manner that effects the object’s
position or scale controller.
The target object can
be any type of object. The rotation of a target object drives the
constrained object. Targets can be animated using any of the standard
translation, rotation, and scale tools.
Multiple Targets and Weighting
A constrained object
can be influenced by several target objects. When using multiple
targets, each target has a weight value that defines the degree
by which it influences the constrained object, relative to other
Using Weight is meaningful
(and available) only with multiple targets. A value of 0 means the
target has no influence. Any value greater than 0 causes the target
to influence the constrained object relative to other targets' Weight
settings. For example, a target with a Weight value of 80 will have
twice the influence of a target with a Weight value of 40.
Once you assign an Orientation
constraint, you can access its properties on the Position Constraint
rollout in the Motion panel. In this rollout you can add or delete
targets, assign weighting, assign and animate target weight values,
and adjust other, related parameters.
NoteWhen you assign an
Orientation constraint via the Animation menu, 3ds Max Design assigns
a Rotation List controller to your object. In the Rotation List
rollout list you will find Orientation Constraint, which is the
constraint you assigned. To view the Orientation Constraint rollout,
double-click Orientation Constraint entry in the list.
- Add Orientation Target
Adds new target objects that
influence the constrained object.
- Add World as Target
Aligns the constrained object
to the world axis. You can weight the amount of influence that the
world target has on the constrained object as you would any other
- Delete Orientation Target
Remove targets. Once removing
the target, it will no longer influence the constrained object.
Assigns and animates weight
values for each target.
- Keep Initial Offset
Preserves the original orientation
of the constrained object. When you turn off Keep Initial Offset,
the object adjusts itself to match the orientation of its target
or targets. Default=off.
- Transform Rule
When an orientation constraint
is applied to an object that is part of a hierarchy, this determines
whether the local node transform or the parent transform will be used
for the orientation constraint.
- Local –>Local
When selected, the local node
transform is used for the orientation constraint
- World –>World
When selected, the parent
or world transform will be applied, rather than the local node transform.
