For the modelling of the spaceship Nostromo from one of my favourite films – Ridley Scott's 1979 Alien – I used official blueprints as reference images and added my own ideas in a couple of places.

After I was done modeling the most important parts of the ship, I used the Plating Generator Add-on to extrude randomly sized and distributed faces on selected parts of the surface. I based the scene of my final render on a screen capture from the original film.
