What should I do if "No camera in scene" is displayed when I press the c key in 3ds Max?

By default, there is no camera in the scene, so the C key cannot be selected. You can press the shortcut key Ctrl+C to create a camera from the view, or create (Create)__Camera Create it in the menu. Then press C in the activation window to jump to the camera view. If there are multiple cameras, the camera selection will pop up
