Hello everyones !
I’m a bit disapointing, i have made a gui for a game, it is a canvas with many text zones, i have put the canvas in the camera and set it’s render mode in world space as i found in a youtube video.
The problem is when i move the camera the canvas simply disapear from the game window and come back a few frames later or simply don’t come back until i make the oposite translation with the camera…
How can I fix this ?
Please help ! 
Okay Problem Solved !
I move back the canvas and i works fine now. I suppose it was too close to the camera.
