You can split your nCache clips to divide an object’s cached simulation into multiple, reusable cache clips.
You can not split a cycled nCache clip. You need to first merge the cycled cache clip before you can split it. See Merge nCaches.
All the current object’s caches appear as clips in the track view.
The nCache clip is split at the current time indicator’s current frame and two cache clips appear replacing the selected cache clip.
The nCache clip is split according to the current settings in the Split Clip Options window, and two clips appear replacing the selected cache clip. See Split in the Animation guide.
