CGTextures - High Quality Web Materials

CGTextures is a pretty good material website, the pictures in it are of high utility value and quality. As a plane designer, without better quality materials, the creativity of the web page will be greatly discounted. Instead of spending hours on websites looking for the material pictures you need, you might as well go directly to CGTextures, where the categories are clear: animals, stones bricks, buildings, fabrics, metals, nature, rust, paper, etc., quite detailed.
