yep i will post it but it might not get there for about 2 week as im on holididay in a couple of hours. to tweak it go under specular shading and go to box of reflected colour. click the box that takes u to its attributes and chose a new image this will relect off the metal and changes it colour slightly but dont worry. also tweak reflectivity at the moment its about 0.500 but changing this will also make big changes. . its not the best shader so if u tweak it u should get it looking pretty good.

if download doest work im soory in advance
