The above image is the final result. I recorded the process I took, unfortunately the quality is whack (Vimeo basic only allows 1 HD upload per week) but I'll show the video anyway.
The texturing part is pretty damn straight forward, it's the same technique I used for the brick pattern so it's not all too different except, it's metal not brick.
Hopefully people will find it useful. It was fun to make.
I did initially record a voice over but because my mic is so bad I ditched it until I can get a new one or find my better one which is probably still in storage somewhere.
