Hello, I wanted my first post to be on this thread for a number of reasons...first and foremost to say thanks to all who made this happen, because as a 3d modeller(of sorts), I have wanted to see how the namco fellas did their models for YEARS, and finally I get to! After reading the thread, I tried everything as instructed and it worked perfectly. I now have nina imported into 3dsmax complete with textures(although I too noticed the textures needed a little tweaking in the V&W but that's not a big deal at all, and certainly not a complaint

). I'm currently converting her as a model replacement for my left4dead2 game (lol!) so she can kick zombie butt as well hehehe. At any rate, as an attempt to contribute just a little tiny bit, I thought I would run through my method, etc (since it's still fresh in my mind) for those having trouble. A noob trying to help out the other noobs you might say...so here goes...
I have a folder called tekken6 and in this folder i have noesis, xbcompressiontools, and poopypants.exe (best name ever!).
So that folder is where my tools live and where I will put the bin and idx files and the raws and nmds later.
so first things first...I insert my tekken 6 disc into the drive and load up xbox backup creator...of course I have a special drive with a hacked firmware which allows me to read these discs(i guess this really goes without saying but anyhoo)...
so I go to image tools then image browser....
now scroll to the file I want(nina!!) so that's data306..
I highlight the bin right click and choose extract then do the same for the idx...i put them in my tekken6 folder...
Now I open a command prompt and go to the tekken6 folder and run xbdecompress /H /E /D data306.bin (yes to overwrite)
it runs for a bit then finishes...
then i run poopypants data306.bin and that extracts all the raw and nmd files
del the raws cause i don't need them
load noesis and go through the nmd files (the largest are my focus cause they're most likely to have what I want-full character)
once I find nina I go to file/export and choose smd/tga options and let it do its thing.
voila...i can now load the smd file into 3dsmax and fix all the textures that need it(not all do).
so I repeated this exact process, as instructed in the thread, for christie, xiaou, and jin(who required a little more putting together but no biggie) and it works like a charm.
so anyways, I hope that can help someone having troubles...
I'm using win7 ultimate 32bit btw & xbdecompress6534(as instructed)
you can mod the textures(once you get them out)after doing this and I suppose you could find the vehicles too if you looked hard enough...there is a post in here with a general overview of what's in some of the bin files...that's how i knew which one had nina...so i would start by reading that...at the very least it will tell you which files they're not in
hope this helped someone...somewhere....lol
