I actually started that very project a couple years back, and my computer ran out of memory to complete it.
Yes, ran out of memory. It was in HD and used more than 10,000 still images. Every single part was animated/illustrated (to scale) so I could assemble images of any portion of the weapon in any position.
I did just recently get a new fangled 64b-bit machine with 8 times more memory.
Perhaps I should open that file up and see what happens?
Still needs some work before completion, so, no promises.
