I have some animations from fab which are based on SK\_Mannequin skeleton, but it has additional bones in it. For example, R\_HandSword

And I have my character which is also based on SK\_Mannequin, but it doesn’t have those bones. I manually added R\_HandSword to it with unreal skeletal mesh editing tools to the same parent bone.

However, when I try to retarget animations, the R\_HandSword bone on my character isn’t being animated.

How can I fix this?

Are you using IK Retargeter, and have you added these bones to the bone chain and set up the mappings?

Thanks for reply. I found the solution. In my case the bone has translation animation. And I needed to set translation mode in retargeter chain setting. It is set to none by default.
