Beam Superposition Issue

So, i would like to make a screen. For now, no issue.
I use a beam to make some sort of Screen effect, no issue so far.
Then i want another beam to add an effect when my screen show some info such as a warning. That’s where the troubles begins:

  • When i’ve got 2 beam, different position, origin point… name it it’s different, but for some reason, one beam can overlay the other one, only depending the camera angle ?

here’s a video to understand the issue

In text: You got 2 beam, BEAM A and BEAM B. Beam A is in front, while Beam B is at the back. The order of appearance is supposed to be A then B. As you can see on the video, depending the camera angle, Beam B sometime goes in front of Beam A, despite having different Coordinate and such… so i’m not sure if it’s a game engine bug, or am i doing something wrong ?

there’s something with the Zindex or whatever it’s called. try giving one 0.005 more of a value than the other one.
