The Leather procedural texture allows you to easily replicate a leather textured material.
ScaleThis controls the scale of the leather grain.It is highly suggested that you add a synced procedural leather bump to further simulate realistic leather.
Color 1This is the color of the high points (bumps) in leather. This color should be lighter than color 2, but it should be as close to color 2 as possible for realistic looking leather.
Color 2This is the color of the low points in leather. This color should be darker than color 1, but it should be as close to color 1 as possible for realistic looking leather.
In this example the Leather texture is applied both a diffuse and Opacity map.
