How to place actor at edge of screen using BP?

Development Programming & Scripting Blueprint

I created a custom blueprint node for that returns the world coordinates for the centers of the top, left, bottom and right frustum planes.

To test it I’ve made it so that at game start a fire particle is initiated at the center of each of the planes. The cube represents the camera position.
