Looking for documentation about integrating a camera manager

So I’m trying to set up the camera system from ue4’s dynamic camera article,

[Six Ingredients for a Dynamic Third Person Camera - Unreal Engine][1]

I’ve got most of the code that I want to use and I’ve set my character controller blueprint to use the player camera manager class I set up.
I’ve also set up a view target with blend on the tick event of my controller but now my controller is not interpreting my inputs. (So I have to make an edit here) It turns out I can still move the character. I have a dedicated spring arm component that I will try and implement on my own. I still want to keep this up because the main point of this post is getting help finding documentation about this concept.

I haven’t been able to find decent documentation about using these two classes together. Lastly, a code solution would be preferred but if using blueprints would be better for this that would be good also.

Any help will be appreciated. Thanks
