There's a game coming out at the end of the month that runs on Unreal 4. I want to steal a model from it to use as an avatar in VRChat and whatever platform the community decides on.

What do I need to do in order to do this? Is it something I could do with a guide or am I gonna need to hire someone? I guess I also have to extract the model and texture, which I'm also clueless about.

I don't expect to be spoonfed, I'm just trying to get an idea of how big a task this is and what steps I might be overlooking.
