GtkRadiant/Shaders

Shaders are short text scripts that define the properties of a surface as it appears and functions in a game world (or compatible editing tool). By convention, the documents which contain these scripts usually have the same name as the texture set which contains the textures being modified (e.g.; base, hell, castle, etc.,). Several specific script documents have also been created to handle special cases, like liquids, sky and special effects.
