If you are seeing error messages during startup or FlightGear doesn't start up properly, it's probably because you don't have enough free video memory. Reduce the size of the shadow map in preferences.xml by locating  

  <map-size type="int">8192</map-size>

And put 4096 or 2048 instead.

For material shaders, it is necessary to provide both <tt>gbuffer-functions.frag</tt> and <tt>gbuffer-encode.frag</tt> in the effect file, like this :

<program>

<vertex-shader>Shaders/ubershader.vert</vertex-shader>

<fragment-shader>Shaders/gbuffer-encode.frag</fragment-shader>

</program>

For fullscreen passes shaders, only <tt>gbuffer-functions.frag</tt> should be provided, like this :

<program>

<vertex-shader>Shaders/sunlight.vert</vertex-shader>

<fragment-shader>Shaders/gbuffer-functions.frag</fragment-shader>

</program>

In the main function of the shader, the functions referenced need to be declared first. With no #include files, the whole function prototype needs to be typed :

void encode_gbuffer(vec3 normal, vec3 color, int mId, float specular, float shininess, float emission, float depth);

     encode_gbuffer(normal, color, mId, specular, shininess, emission, depth);

}
