5 Do one of the following:
■ Drag to the right within the selection to expand time from the left
edge of the selection. All keys to the right of the selection slide right
as the selection expands.
■ Drag to the left within the selection to reduce time towards the left
edge of the selection. All keys to the right of the selection slide left as
the selection shrinks.
■ Drag past the left edge of the selection to reverse time and expand it
with a negative scale factor. Keys inside the selection, and keys to the
right of the selection, can overlap keys to the left of the selection.
Exclude Left End Point
Track View > Dope Sheet > Extras: Dope Sheet toolbar > Exclude Left End Point
button
Use Exclude Left End Point to exclude the beginning key in a selected block
of time.
If you paste the same block of time repeatedly, one block following the other,
you can create a looping segment in your animation. To create a smooth
looping animation, you need to exclude either the first or last key of the copied
block to prevent keys from doubling up at the ends.
The key to be excluded must be at the exact start time of the copied block of
time.
NOTE By default, the Extras: Dope Sheet toolbar doesn't appear in the Dope Sheet
Editor. You'll find a method for displaying it in the following procedure.
Procedures
To animate a loop by copying and pasting keys:
1 In Dope Sheet mode, highlight one or more item labels in the Controller
window to specify tracks for time editing.
2 Use Select Time on page 3630 to specify a block of time.
