Position Ranges mode
allows you to position range bars independently from their associated
keys and produce special effects.
The process of adjusting
a range bar independent of its keys is called decoupling the range.
Positioning a range bar so it matches the first to last keys of
a track is called recoupling the range.
The Ranges: Dope
Sheet toolbar doesn't appear in Track View by default. To open it,
right-click an empty area adjacent to the Dope Sheet toolbar and
choose Show Toolbars
Dope Sheet. Save your layout after you do.
Decouple a Range Bar
You decouple a range
bar for two reasons:
- You want some keys at the start or end
of an animation range not to take effect.
Keys outside of the range
bar are ignored during animation playback. The keys outside the
range still affect interpolated values inside the range, but the
applied Out-of-Range type is used to animate time outside the range
- You want to add extra time before the
first key or after the last key that is not affected by the applied
Time beyond the first
or last key of the track, but still within the range, uses the constant
value of the nearest key within the range.
To decouple a range bar from its keys:
- Right-click an empty area adjacent to
the Dope Sheet toolbar and choose Show Toolbars Ranges: Dope Sheet.
- On the Track View toolbar, click (Position Ranges).
- In the Track View Key window, drag the
entire range bar left or right of the keys, or drag either end of
the range bar to make it longer or shorter than the keys.
types in conjunction with this procedure
allows you to change the behavior of an animated loop. Positioning either
end of a range bar changes the loop.
