Wall? Auto UV Map Box Modifier + Builtin metal texture.

The only things I really need to UV are things like Computer screens, buttons, logos, etc. And for those it's really just to fit a very basic square image so a flatten UV command usually does the trick. Of course, that means none of this works if you view it from angles other than intended. But that doesn't matter here.
