Third Person 'Survival' Camera - Issue With Strafe Whilst in Default Cam

I’ve tweaked this so that now the rotation of the actor only updates when the character is being instructed to move (see blueprint below). The problem I’m having is blending the character, as he now snaps to the new rotation. I’ve tried using RInterpTo and so on, but either its not working, or I’m not doing it right.

Would anyone mind showing me a correct way to have the character rotation blend between its current direction and the camera direction?

Thanks.
