first of all thanks a lot for any advice or help. Really appreciate it!!
In the first picture you can see a simple cylinder. This one I want to render with steel material (second picture) Although the steel sanding should be radial not in one line like it is in the second picture. I tried using texture mapping and looked into the diffuse material for changes, without any success. So I really hope someone here can help me out. I think it shouldn´t be such a big problem.
Thanks again, looking forward to an answer.
