Hi all, I am trying to get a Dragger on my HUD display, but I am not able to manipulate it at all. If I add it the identical dragger to the normal scene, it works as expected. Any insight in this is appreciated as I have reached the end of trying to traverse the scene trying to gain understanding in this matter.
