I’m having the same issue after applying facial animation. This is so messed up! They keep promoting how awesome it is to animate in the engine and then this happens!!! Ugh Anybody got a fix for it? I’m using UE5.03, Omniverse Audio2Face and motion capture animation for the body.
Fix: save everything and restart the engine
However, it will happen again if you add another facial animation clip… if it does just save everything and restart the engine
