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);

main() {

     vec3 normal;

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

}
