It just depends on the number of facets you used to model your aircraft. You already know that a model is made of triangles and quads and if it looks rounded, it's only because colors are interpolated between vertices, depending on normals. If you remove the 'smooth' attributes, you'll see that a quad is fully lit or fully shaded because its normal point toward the sun or not. -Fred -- Frédéric Bouvier http://frfoto.free.fr Photo gallery - album photo http://www.fotolia.fr/p/2278/partner/2278 Other photo gallery http://fgsd.sourceforge.net/ FlightGear Scenery Designer ------------------------------------------------------------------------- Using Tomcat but need to do more?
