Some aircraft designers look at the X-Plane view type to determine how much to render. As an example some of the Flight Factor planes will not render the exterior properly if you simply place a 3D cockpit camera out side the plane.
X-Camera has a camera option called “External Camera”. This option uses the X-Plane free camera view which will allow the correct rendering of the plane’s fuselage. Open the Control Panel and check the “External Camera” option for any external views.
