I'm working on a project where I intend to build a highly detailed model of the spaceship Serenity based on its appearance in the movie Serenity from 2005. I did an exterior model years ago but always wanted to go through and do the interior in high detail along with redoing the exterior model. The first stage of this is to block out the interior, which takes a lot of time to make sure all of the dimensions are correct. There's not a lot of supplemental reference material so I mostly had to rely on screenshots from the movie. A company called Quantum Mechanix made some blueprints a while back, but they had to make drastic changes to the interior to make things fit so those blueprints were useless for the most part.
After this I intend to do the full detail modeling and then finally do texturing and lighting. After that I'll go back to the exterior to make a better model of that part.
