Types of constraints
Set Driven Key-Constraint blending
Animation-Constraint blending
You can blend keyframe animation and constraints
on the same object. See
Animate and constrain an object and
Animation-Constraint blending workflow.
When both keyframe animation and constraints
are applied to the same object, a pairBlend node
is automatically generated. See
pairBlend. All
the object’s animation and constraint channels are linked to the
object through this pairBlend node.
You can modify the weight of the animation-constraint
blend to generate various effects. This Weight attribute
is on the pairBlend node. See
Blend Weights in the Channel Box.
Note
- Since
animation-constraint blending lets you transform the constrained channels
of a driven object, you must lock the constrained channels that you
want strictly influenced by the target objects.
- After
transforming a constrained object, you can retain its new translation,
rotation, and/or scaling by reapplying Maintain Offset from
the Modify Constrained Axis Options window.
This prevents the constrained object from snapping back to its original
translation, rotation, and/or scaling when its target objects are
transformed.
Animation-Constraint blending
examples
- A man runs to a parked convertible car, jumps
over the door and into the driver’s seat, and then drives away.
In this example, both the character and car models are animated,
and various parts of the man are point constrained to the car’s
door, seat, and steering wheel.
- A basketball
player dribbles the ball, picks it up, and throws it to another player.
The player that catches the ball pauses and then shoots for the hoop.
In this example, the ball and all the players hands are animated, and
the ball is parent constrained to the various player’s hands.
