How to modify the times of the animation curves.
Cycle sections of animation with a time warp
To change the range of animation to be cycled
A new time warp curve is created that will be applied to all specified channels of the selected animated items. These channels now cycle through the animation between frames 1 and 30 twice before continuing on with the remainder of the animation.
An alternate way to cycle the complete range of animation on a channel for an infinite (or undetermined) number of times is to use the Cycles or Oscillate out-of-range type on the base action of a channel, instead of applying a timewarp. See the Action Tools menu items in the Action Window. For more information on timewarp curves, see
Scale animation timing with a time warp
To set new scale warps
These channels are now all scaled by 2, which means that their animation now takes twice as long to play back.
