Hi. I’m using Unity 5.5.1 and I create 2D games. Since I only need Canvas, should I add a camera since camera is useless and I don’t use it? Because When I delete the camera, the message “display1 no cameras rendering” and it’s annoying.
you don’t as long as you render over the whole screen all the time (background image). you’d otherwise need it for clearing the screen with a color or skybox, unless you do that with a GL call.
the easiest way to keep the camera is leaving it while editing and tagging it “Editor only”
