The value of the new key is set by one of the following conditions:
Keys added before the first key of a track receive the same value as
the former first key.
Keys added between two keys receive an interpolated value based on
the values of the original keys.
Keys added after the last key in the track receive the same value as
the former last key.
If you are unable to add keys to a track, check the following conditions:
Only animated tracks can accept keys. If you want to add a key to a
track, such as an object parameter, you need to animate it first.
The animation controller must be a type that uses keys. Not all
controllers use keys. Examples of controllers that do not use keys
include procedural controllers such as Noise.
The animation controller must be a type that uses keys. Not all
controllers use keys. Examples of controllers that do not use keys
include Expression controllers, List controllers, and Parametric
controllers.
Properties (Track View Key Window)
Track View > Highlight a single track that uses Properties. > Right-click the
track. > Choose Properties on the Controllers quad.
Track View > Highlight a single track that uses Properties. > Controller menu
> Properties
Properties displays a dialog to change animation values. The type of dialog
displayed depends on the type of animation controller the selected track is
using. The Properties function is unavailable if the selected track controller
does not use properties, or the track selection set is incorrect.
A track with animation keys display a
Key Info dialog on page 3127. You can
change the values in the Key Info fields to change the animation value,
time, and interpolation methods of one or more selected keys.
A track with a parametric controller, such as Noise on page 3214, displays a
Properties dialog. You change the values in the Properties dialog to modify
the behavior of the controller over its entire range.
