Camera Zoom In-Out with Focus Track (or simply change Focus Distance) on my Third Person Character

[Vexar]

you just need to write a BP to look at the values of the current focus distance and change the based on what you want for the zoom in and out, if it is a % or a fixed value 5 to 100 or X% when ever the zoom value changes you adjust the focus distance per your vision of what you want.
