I am modeling an Iron Man http://blenderartists.org/forum/showthread.php?t=186653 , i have mostly finished the helmet and, applied some basic materials, but when i try to go beyond(materials), i can never get a good result.
I know the metal texture has reflectivity, but i do not want to use an hdri, just a gradient black/gray background.
I also need to make the materials look like metal instead of plain colors.
Also some scratches here and there would add realism.
So this is what i have in mind, but i have no idea how to achieve, i poked around on the internet with no luck, perhaps someone could point me in the right direction?
Here is what i have so far(left image) (more renderings on my modeling post)and a similar result i want to achieve(the other 2: movie poster and front/back image):
Any help is GREATLY appreciated!
Thank you in advance.
