Hi, I can’t answer the main question, but for knowing how centered an actor is maybe you could use the Deproject() function and compare the position of actors relatively to the screen dimensions, and maybe a Trace from the camera focus would help with the relative scale/size of the actors in the capture. Just general suggestions, I don’t really know if they are the best way to achieve that, as I haven’t used much C++ with UE4 for now.
