Rotate first person character around object

Hello everyone:)

I’m really newbie in UE4, so pls help me with my issue, it’s really important for me)

What is my objective - I want to rotate my first person character around building by clicking on buttons. For example, button right is for rotating camera around building by 90 euler degrees.

Of course, I want to do it smoothly, so rotate must to take some time. I’m use RotateVectorAroundAxis, but what I’ve got - is just vector value of point I need to move. Please, help me with this blueprint, how can I move to this point smoothly (without event tick preferably). Or maybe there is a workaround to do this.

Thank you:)

Easy way to do it is create another camera, maybe someone can help you with that without add camera…
