I'm trying to create a chainmail pattern in Cycles by creating interlinking chains, and then baking them using an Emission shader to generate a black and white image, to then use as a Bump Map and mask to generate a mail material and texture. I only modelled two chains and then used Arrays to make copys of them.

The problem though, is that I can't seem to align the Camera in a way that generates me a seamless texture.

As you can see, the result is not seamless and it's very obvious, so how can I align the camera perfectly that makes the baking a lot more easy.

Two things to make it work.

1. Make your camera Orthographic
This will help you avoid distortion in corners, and will make it 'infinitely flat'.
It's like using an infinitely long lens.

2. Make the array 1:1 aspect ratio
Your chainmail array is ever so slightly taller-than-wide.
Move the rings a bit along the X axis, so they fit nicely.

Voilá. Seamless.

Notes
If you want the mail evenly-spaced, you'll have to adjust the whole array (I was just lazy).
I also moved the camera a bit, instead of moving the whole array.
