Oh well, but thanks. That's what I was thinking. Finding sides and use em to build the model although that won't be perfect but it will work just fine. There's an alternative, which involves in hacking the file (where the model is located) and extract it, but that requires a whole different level of ball game: what if it's compressed? What if it's encrypted? Afterwards, I guess it's all about learning the file format and structure and then map the data at certain offset (s) and whatever else in order to extract the 3D model. Which can be challenging since a lot of video games use different file formats and structures.
And to the other poster, your last sentence was a bit offensive. So, no thanks to you.
