Where can I find this node in Blueprint?

Where can I find the red colored node named by “Cast to Player Controller”? I have not seen such node.

Looks like a basic cast, aside from having an event node color and built in function icon. User generated node from C++?

Where did you see it referenced at?

That’s a custom function that someone wrote for their blueprint. With macros you have the ability to change the color of the node, I’m thinking you can with functions as well.
