Here is a model of a SCF 28 Skymaster orbital freighter, that I found in a Sci Fi art book.
The first pic is the original line drawing from the book that I bought back in 1978.
The second is the completed hull with default materials in Hex.
Third is a test render.
It only took me a day to get this far, from scanning in the picture to UV mapping the hull.
I still need to make the interior and make the texture & bump mats.
When finished, I plan to put it up on my freebie page on sharecg.
