Hi Cyrille  gemhead -1 works perfect  but i got a question , which is the equivalent of gemhead -1 in pure opengl? i would like to apply the same trick in other programs i made with opengl and other programming languages . thanks.

render your square with a negative gemhead.
[gemhead -1] will be rendered after all other gemhead, but it will also be rendered in the same place, whatever the camera position.
