Getting Relative Rotation of Camera Boom

In version 4.16 it was possible to get the relative rotation of the camera boom, like so:

It was an easy and reliable way to rotate things relative to where the player is looking.

Now, here is the problem, since version 4.17 the relative rotation is always 0 0 0 (or 0 90 0 depending on what the parent is).
They seem to have changed how the camera rotates around the player / how the camera boom rotates.
So, what I need is the rotation of the camera boom relative to the player, but I can’t figure out how to get my hands on the rotator. Any Idea how to receive the rotation the “view direction” relative to the Player Character?

I think I have found a workaround by getting the control rotation of the player character instead.
Other suggestions are still appreciated of course.

Same problem here. It was so simple before…

This workaround may work, thank you…

I’m having the same issue with 4.17 and 4.18… no matter how I set (Use Pawn Control Rotation, Inherit Pitch/Yaw/Roll)… I’m fairly sure this is a bug. In my setup (especially with camera lag and rotation lag set to ON) I don’t think the workaround is suitable…

Sorry, but I think that Player Control Rotation is quite different from Spring Arm Relative Rotation… I’d be happy to be proven wrong though.
