Finally got down to fixing this model. The way it was ripped made it so parts of the mesh were detached from other parts, so I basically had to join everything together again and then texture it. I had to make my own texture for the buttons on his suit, 'cause I couldn't find any texture for it in the files, and (comparing it to how he appears in the game) nothing really fit, so I just created my own for him.
Now I must tackle the process of rigging him again. If I succeed, I may have a new render out later tonight!
