Texturing the mech

Time was running out and I had not even started texturing.  For once I had a vision of what the mech would look like so I made a few layers in photoshop,  a base metal texture, rust texture and a camo paint layer.  Just before I start the texture I decided to try and make a ambient occulsion map.  My first attempt failed as I tried to bake the OA map from the mech itself onto itself which a fellow uni student suggested.  However, after a search on the internet, I found a nice and simple way that required setting up a seperate shader and using the mental ray settings to render and bake I final had a nice OA map to overlay on top of my photoshop texture.  Below are screenshots of the OA mech in Maya.
