Hi, I’m making a VR app for Quest 2 and 3, I have a WorldSpace canvas where a script raises points as if they were the points of a sonar, there is an axis drawn on a texture and points are drawn dynamically loaded from a CSV file in that canvas, giving play in the editor on the computer are displayed perfectly.
When I compile the app in Oculus according to an internal debug that I created the points are created, they load the image but I don’t see them in the canvas, and I don’t understand why, it’s as if I drew them somewhere else, but I emptied the scene, I left only the canvas and the camera, but the points are not visible anywhere.
I don’t understand why, if someone needs more data, see the script or something similar tell me and I’ll post it. Thank you.
