FlightGear 2.0.0 introduces Effects, a powerful way to use Shaders within FG without having to write C code. As of March 2010, FlightGear CVS has a Normal Map effect (Effects/bumpspec.eff), which provides both bump mapping and specular mapping. This Howto provides a tutorial on using this Effect for aircraft. Similar techniques can be used to use other Effects on aircraft.
