Thank you. The problem is as you said, the hidden frame is the reason I cant move it backward.
Also is there way to copy, paste frame on unkey bone ?
- For example, a Weapon that un-key in the whole animation 1 , But my character use this weapon in animation 2, and I already key it in animation 2, when I copy and paste frame from animation 2 to 1, that weapon still didn't have an key at all in animation 1.
- Most of the other animation program usually auto-key the un-key bone to the copy frame if that bone already have a key in the orinal frame.
