This reference image shows that there are a few of the fuel tankers in a farm area near the edge of the harbor. These objects will be good for when the explosion scenes happen and the smoke and fire occurs during the animation - as we can assume that these went up in smoke very quickly.
A ladder and some piping around the edges has been added to make it look more realistic. A metal texture for the piping and the ladder will be simple to apply as they are all seperate objects, but for the main tank, Unwrap UVW will need to be used again so that all the materials look effective. Also, as a door is being added in at the top of the tank, different materials will need to be applied to this part too.
I have mapped this building first mainly so that I could get some more practise with the Unwrap UVW technique. This building was very simple to flatten and map out then apply the materials in Photoshop, which might not be the case with the more complicated buildings. The most complicated thing that needed to be done was for the top and bottom circular sections: there were no appropriate aluminium textures that matched up with the rest of the building to apply without having a watermark, so the first task was to remove it using the clone brush on a very small setting.
After this, there was a lot of rotation and referring to the mapping in 3DS Max to ensure that the right parts were being selected, but there wasn't a major need to change materials as the piping and ladder had already been sorted in the program using UVW Mapping. The final texture was then applied to a black background and the outline layer was removed.
The final building then looks as follows. This will be cloned, rotated etc. when I work with the landscaper and put the buildings into the landscape to form the basis for the scenery.
