A shader like this. I have done the shader, but I would need bond1's permission to give out the shader as it comes with the metro pack. So bond if you are reading through, I know you said wait six months before releasing stuff using the shaders from the metro pack. It is one of your dynamic heros spec shaders. Permission please.
But I can just give out the textures I made to use the shaders. For the shaders use spec_normal_herospec.fx or play around with the rest of them to get what you want.

Best I think shader I think.
