| | The [[https://icculus.org/gtkradiant/documentation/Q3AShader_Manual/|Quake 3 shader manual]] states: |
| | |
| | // |
| | 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 that contain these scripts usually has 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.// |

| | |
| | |
| | For Tremulous, .shader files are located in the //Tremulous/base/scripts// folder |
