[Tutorial] How to rip PS2 models v.2

[Branhernan]

Hey guys, I've been trying to Rip the colossi from "Shadow of The Colossus" and I haven't been able to rip them, to me it looks like a whole lotta wireframes with no discernible figures, I was able though --after around 20 attempts -- to get a distinct figure which turned out to be "Wander", the protagonist, so I isolated him and for some reason he's as flat as a pancake, his side is fine but his front is just... flat..., so, I was wondering 2 things,

1.) Why is he flat and is there any way to fix it?

2.) Can someone help me rip Valus (or tell me how to locate his model through a bunch of wireframes)

Please and thank you
