Why does this happen for the mentioned bones? And how can it be prevented?

Hello,

did you finally find a solution? I have the same issue.

that’s what I feared, thank you for your answer.

Same problem. I didn’t understand. It works for everyone on video. I have no. What kind of skeletal mesh will this work with?


Unreal 5.1 still got this problem. Anyone find a solution?
