My understanding of this is that the Xbox models are required, because those are the ones with a script written for them to get them into 3dsmax....I'm guessing the PC TMC/TMCL files are encrypted differently perhaps? Then i presume the Xbox models are forced into a PC usable file. Lol, I could be wrong of course, but that seems to be what Harry is saying.
@Harry: you have my thanks for your work anyway, and as much as I'd love to see your work 'completed' by the community it makes me angry to see people calling you lazy or selfish- obviously the reverse is true as you've already sunk many hours into making and sharing a mod thats made many many peoples lives happier, including mine. Thank you.
(edit) Please note I'm not trying to point any fingers at anyone here, its just a general vibe i've picked up across a couple of forums, a few sulky complaints made that probably shouldn't have been made, and when I read them it made me feel for Harry, who after all opened a door for us that no-one else could or did.
