Hiya.

Uh, what? Do you mean a "game engine"? Or an internal combustion engine? Or how to make a working internal combustion engine in 3D Game Studio? If a game engine, do you mean how 3DGS works, or some other game engine?

Could you re-write your request, eplaining a bit more...I (and others i'm guessing) don't know what you are asking.
