• The last frame which have orange color cant be move backward. This bug happend when I copy animation and the copy one have this bug. Now even the non-copy animation also have this bug. And this bug happend very frequently.
• Hope you guy can fix this bug soon enough. :yes:

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.
