Bumpy Copper FStorm Shader

This is a copper shader mixed with a leather like bump map.

This was not created to imitate faux-leather effect of some modern synthetic fabrics but to give a unique bumpiness to a realistic copper and get a different copper style than what we are used to find for this kind of shader.

Software used is 3dstudio MAX 2017 and FStorm 0.38a but it will be compatible with later versions of both.
