Before we begin, I want you to know that this tutorial won’t do you any good if you don’t know the basics of Blender, and that includes handling skeletons.
I won’t cover these here, there’s many tutorials for that on the internet. Either ask, or search for an answer in Google.
Also, have in mind that most of this is more like a general guideline, you might need to adjust some steps depending on what you’re importing, since not every game has the same standards when it comes to assets of any kind. That said, in my case, I’m importing Christie from DoA 5 LR, and not even in this game do all the characters have the same standards.
