How to know location of mouse click?

How can I find the precise location of an actor w.r.t the center of the world when I click with the mouse in a position?

I have a table centered in the center of the world and with a vertex in position (100, 100, 100), but if I click with the mouse on the vertex it gives me strange values and not (100, 100).

Well what are you trying to do? Are you doing a Line trace from the Mouse position & direction in World space?

I think the strange values come from using the wrong function. you might be getting the mouse position in 2D coordinates (referring to screen or viewport position).

If you are using a line trace with Mouse position/direction in World space, then provide some screenshots of the code where you do this check so that I can have a better look at what’s happening
