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 targets.
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.
Procedures
To assign an Orientation constraint:
1 Select the object you want to constrain.
2 Choose Animation menu > Constraints > Orientation Constraint.
3 Select target object.
To access the Orientation constraints parameters through the Motion panel:
1 Select the Orientation-constrained object.
2 On the Motion panel > Rotation list, double-click Orientation Controller.
The Orientation constraint parameters are located on the Orientation
Constraint rollout.
To edit weight values:
1 Select the constrained object.
2 Open the Motion panel > Orientation Constraint rollout.
3 Click a target from the list.
4 Use the Weight spinner or enter a numerical value to set the weight value.
To animate weight values:
1 Select the constrained object.
2 Open the Motion panel > Orientation Constraint rollout, and choose a
target from the list.
