2048 × 2048 JPGs, most of them coming with normal maps, specular maps and parallax maps. If you need smaller file sizes, you can reduce the texture size or compress more aggressively.

Ready for use in Tesseract (.tex files), although they can be used in any other project. The .tex files provide nice combinations of diffuse maps and other texture maps like normal maps, so reading them is a good starting point. You can open .tex files with any text editor.

These textures were made with GIMP and gimp-normalmap.
