A collection of bump, gloss, and glow textures to enhance the original Quake game textures.
Download a release and extract directly into your quake/id1/textures/ directory (create the textures directory if it doesn't exist).
The original pixelated Quake look can be achieved by using nearest texture filtering. This can be enabled with the console command:
gl_texturemode gl_nearest_mipmap_linear
To get the most out of the textures real-time lighting is required. While the map lights can be used by default for real-time lighting, for best results custom rtlights files can be used.
