Missing a Set

I have everything in this blueprint setup, but I can’t find Set…what is the name of it? is it just Set?

Your posts are pretty vague. What are you trying to set/change here?

That requires a playercontroller reference as it’s target, so drag off from a get player controller node and type in Show Mouse Cursor, to find it.
It’s not a special node though, it’s just setting that ShowMouseCursor boolean variable in your player controller, like any other Set node.
