How to edit the timing curve in your Action window.
 | Previous: Set up a camera to travel along a motion path |
1 With the sphere still selected, choose 
Animation > Editors > Action window.
2 Choose the Look At command (Views > Look at) to better view all animation curves.
When you animate an object along a motion path, StudioTools creates a keyframe at each frame of the animation. (Remember, a keyframe is indicated by a red dot.)
There is one diagonal line that has only two keyframes. This is known as the timing curve, and it represents the constant speed of the object along the curve.
To edit an animation along a motion path curve, you usually edit the motion path curve (in the view window) or the timing curve. You don't usually edit the animation curves because they are so complex.
3 Choose the Pick Keyframes command (Pick > Keyframes).
4 Click the last keyframe of the timing curve to select it.
5 Choose the Fast Segment In command (Tangent Type > Fast seg in) to change the tangent of the timing curve at the selected keyframe.
The diagonal timing line is now curved. This will make the object begin moving very slowly and gradually increase its speed.
6 Click the top left corner of the Action Window to close it.
1 Pick nothing to deselect all objects
2 Choose 
Pick > Object and click the motion path curve to select it.
3 Select the box beside the Control command (ObjectDisplay > Control 
) to open the Object Display Control window.
4 Set Scope to Active and make sure that only the Hulls and CVs options are on, then click Go.
5 Click Exit to close the Object Display Control window.
The hulls and the CVs of the motion path curve become visible.
6 Pick nothing to deselect all objects.
7 Choose 
Pick > Point Types > CV and click one of the motion path curve's CVs to select it.
8 Choose 
Transform > Move and drag the right mouse button up to move the CV up.
The CV is moved up and the shape of the motion path curve is changed.
9 Pick nothing to deselect all objects.
