I would guess no, as your actual in game 3d character is rendered by the graphics engine at runtime.
Without googling, I'm assuming you'd have to find a white wall in the game, and using video out, record your character turning around, then feed that into some sort of 3d modeling software which could hopefully map all the major points/textures on your character, much like the 'magic wand' feature of adobe photoshop or fireworks maps the outline of 2d graphics.
But if there is some 'easy' way, that'd be nice hehe. I can think of all sorts of amusing things to do with 3d models of eq chars
Whats the final form you need it in? Most folks that make custom movies either record the video on the screen, or use the video out line from their video card to record straight to hardware, but then you just have a movie, not an isolated 3d model to work with.
