- Attach an object to a motion path curve, as described in Attach an object to a motion path.
- Select the object only, and view the INPUTS section of the Channel box.
- Select
motionPath1 in the
Channel Box. This is the node that controls the path animation.
Its attributes appear in the Inputs section of the Channel Box.Note: At the start of the path, the object's U Value is 0, and by the end of the path, its U Value is 1.
- Select the
Show Manip Tool
from the tool bar (or select
).
A manipulator appears around the object.
- Use the
Motion Path Manipulator in one of the following ways:
- Use the handle in the center of the manipulator to move the object along its path.
- Use the handle on the circle to control the front twist attribute of the path animation, that is, the amount it twists around its front axis. This latter handle can be used to manually set the banking of the object.
- You can click in the time slider or click the light blue centre handle of the manipulator, and drag the object along the path to advance the object to the next motion path key.
To set keys along the path:
- Position the object and, set a key for the U Value attribute of the motionPath1 node from either the Keys menu, or by clicking on the U Value attribute of the motionPath1 node in the Channel Box and selecting .
- Click the Play button in the Playback Controls to view your path animation.
Tip:
- Turn Auto Key on to avoid having to repeatedly set a key for the U Value attribute in the Channel Box.
- This workflow also works if you want to animate the banking of the object by using the front twist handle of the manipulator.
