How do you port models from a game so that they can be used in gmod?

im looking for someone who knows how to port models into garrysmod from another game. an example would be taking ragdolls from mafia 2 and making it so that they could be spawned into gmod. PLEASE HELP!

Wrong section. This belongs in the modelling section. But anyways, you have to be moderate in a modelling program like 3ds max or blender to do things like porting. Its not very easy.

If you have to ask this chances are you’re unable to do such a thing. It’s not an easy process. But yes, what the above user said. You’ll need a program like 3DS Max, Blender, or Maya.
