Custom nameplates/billboards in 3d worldspace

Thank you for your answer. Yes, thats what i said - i can use simple UI widget in screenspace, to make sure, that the text isnt blurry or got artifacts. The big problem is, if i make this in screenspace, then the widget is always over the screen and not cutted. You can see it in the video what i posted. There you can see, that the text is behind other 3d objects… thats the main problem, or i missunderstood what you mean.
