How could I get rotator from the Joint.Orientation?

I want to rotate a bone, but don’t know how to transform the matrix to UE rotator, please help, thanks!

Hello @TGzzZ
Perhaps this wonderful plugin from @Ayumu will help you

Now you can download the plugin from the store!
Using “Nuitrack” in Unreal has never been so easy.
Do not hesitate to ask in case you have any questions
