Model/Missing texture, need help.

First off, I really don’t have a clue as to whether or not this is in the right, or wrong place.
I would reply to this thread, - But It was over a month bump, so, I’m just gonna post here, lol.

So, I followed the tutorial I had linked above, and, well. I had some complications.
I got the model into the game, I happened to be using the Anti-Material Rifle from Fallout New Vegas, but the textures are fucked.

I’ve tried a few different things, and I honestly do not know the problem.
Help is appreciated.
