Hey, im new to all of this, but can you tell me how to rip the models. I cant seem to find anything.

So I have 3D ripper dx, 3ds max, and dolphin, but after I i capture the frame i dont know what to do, or how to convert it into a file compatible with brawlbox.

(Edit): What I am trying to do specifically is rip aang from into the inferno, and another character from a japanese game (Inazuma Eleven Strikers 2012 Xtreme)
