A VITAL step happened before this preview render. All the data of of the Shadow Mobile was zipped and backed up to a seperate external drive. As machines can and do break at any time I thought lets back up the project now instead of waiting for it to be finished.
A number of polygon selection tags were created for each of the backplate parts and then all those parts were connected into a single component ready for UV mapping. I find this so boring but the reward is easier and more accurate painting later on.
Ambient Occlusion (AO) was baked and the AO image used as a dirt mask layer in my paint software. I wasn't that happy with the AO outcome this time and will redo it by hand once the final painting starts.
A few parts have been added to the rear of the Mobile.
