it really is tho i found out how to A-stance the models by deleting there animations helps quite a bit
they normally rip as .rip or something i forgot exact extension its a format specifically for the program but it comes with a 3dsmax extension. you can also rip as an object but its jumbled a bit normally.
happy to help haha
If I had even a bit of experience with stuff like that, I'd try my hand at it.
But right now it just seems too daunting of a task.
