I somehow didn’t animate one leg of this horse. And now I try to put it into correct positions but it don’t remembers it. I select LocationRotation when selecting all bones but it keeps old one. Does LocRot overwrites previus position? Or could it be something else? It follows correct route up to frame 5.
The channel is locked in the action editor. It’s easy to do this by mistake, and easy to miss when you’ve done it!
Just click the padlock icon to unlock, or the shortcut is TAB, with the mouse over the channel list to the left.
Thank you for noticing it, such a folish mistake.
Foalish mistake? drum rimshot
