[Help] Perfectly "Tiling" 45º Metal Texture

Sorry about the long name, but yeah.

It seems the quick and rough method of getting a perfectly tiling horizontal/vertical (noise then repeat motion blur/offset repeatedly until it tiles) metal texture doesn't work for 45º angles.

Does anyone know a method (filter abuse or drawing) to get a quick tiling 45 degree metal texture?

Thanks ahead.

That method works perfectly for horizontal and verticals, but not 45.

I found an almost working solution, though. Just make a proper texture going at the horizontal/verticals, then when it tiles get a square, tilt it by 45 and extract from there and then correct. It almost works, there's a slight pattern-break in it but it's pretty much unnoticeable.
