I want to calc same Rotation when I use AttachToComponent

I’m trying to make HTC Vive games. However, I cannot make any progress…

it is goal image movie on my twitter.(it use AttachToComponent: LocationRule and RotationRule is Keep World)

I need same Rotation result when I use AttachToComponent, without use it node. I think “CombineRotators” node is useful and try it, however, not so good.

AttachToComponent Source is here.
/Runtime/Engine/Private/Components/SceneComponent.cpp

If you have any Ideas, Please tell me!
Thanks.
