How to create a round HUD

Hi all, currently trying to create a gas mask like HUD, as if a mask was over the camera. How could I do that?

u could put a gas mask image in the hud

but what else would you want in it

How could I place a gas mask image in the hud?

It should be possible putting a gas mask image in the hud ( im sure you mean overlapped by the HUD’s?).
If you play a little bit with the add.toviewport and remove from parent til you get the adjustment right.
Tell me if you could fix it with that information, im gonna try it myself if you cant come to an conclusion.
