Apple Shake 4 - Manual (Page 306)

306 Chapter 10 Parameter Animation and the Curve Editor
• The Key field is the time of the keyframe.
• The Value field is the value of the keyframe.
• The LTan and RTan fields control the tangents. If the tangents are set to 0, the
keyframe is flattened (on a Hermite curve). You can also press H to set horizontal
tangents.
The value field displays “-----” when multiple keyframes are selected. To set all
keyframes to that value, enter a number into the Value field.
In the parameters list, the Val field displays the value of the curve at that point in time.
You can also modify the value of a keyframe at that point in time in the Val value field.
For the value to be saved, the Autokey button must be activated in the Parameters tab.

To break the tangents of a keyframe:
m Press Control and drag a tangent end.
To rejoin a tangent:
m Press Shift and click the tangent end.
To reset a tangent:
m Select the keyframe and click the Reset Tangents button.
