One of the Model Editor's main fields of application is to let you visually inspect the model as rendered by the Cafu Engine and as it will appear in the game.
For this purpose, the Scene Setup dialog lets you change the details on how the Model Editor renders the model in the 3D view. Refer to section The Main Window for more information about the 3D view itself.
Camera attributes are rarely entered manually: Normally, you navigate the 3D view as described at section The Main Window, and the camera details update automatically.
