I'm need a low resolution (pixelated) view for my game and am using a render texture, so the camera isn't rendering anything to the screen/game view. To bring the downscaled view to the player I'm using UI Document with a basic UI Element that has the mentioned earlier render texture as a background.
It works just fine, no error occur, besides the message "No camera rendering" in the Editor, so no errors in the build.
But I'm not quite sure if it is a good way to do. Also with the UI Toolkit I don't need a camera for the main menu.
So, is it a good practice not to use a camera in a scene if I have only the new UI (without Canvas)?
