Well, this is an oldie. My first 3D model, to be exact; back from 2003!
The story goes like this: back then I was hooked on GTA: Vice City and loved playing around with modifications that change the functional-but-ugly cars of the game into detailed cars modeled after real ones. But no-one had modeled my favorite car, the Ford GT90. The solution? Modeling one myself.
It took a very long time, since I had to go as I learned how 3D modeling worked, but after some months I finally had a finished car done entirely by me.
Ironically, the car was never properly converted into the game engine, which was its original purpose, but I had found a new hobby.
It was modeled using Zanoza Modeled and has roughly 10,000 polygons.
