Smoothly rotate Poseable Mesh bone with ease

Hello All,
I have been trying to smoothly rotate a bone of a PoseableMesh by name. So far the rotation works just fine, but the transformation is done in one frame.
I have been searching in the “interwebs”, so far I found some people using “Lerp(Rotate)”. That did not make a difference for me.
I attached is my Blueprint excerpt.

As you might have noticed I am trying to rotate a door of car (Skeletal Mesh of car) from it is initial rotation by 60 degrees on the Z axis. I am intending to make the rotation look a bit “natural” :slight_smile:

Any help will be appreciated.
