From what I can tell DanielCoffey (and it isn't much...
), the first two are associated with the zon file and collision / damage system...
The next two are yardarm type thingies, that apparently are missing texture, being the pink and white portions here:
The next two are part of the cabling, and are seen in the picture here as pink, with a white "background", the first apparently being mostly "horizontal" lines, while the 2nd is mostly "vertical" lines, though I am no expert at decyphering the 3D artwork associated with them:
Last but not least, the last is a hidden "hull", of which is another aspect of the 3D artwork that I do not understand.
Someone with more knowledge of things "3D" would have to help further, but I don't know as any of them would be necessary to "see" in the sil image, other than maybe the yardarms, but... from that distance... ??
