I was googleing around and I spotted the LTB2X converter (nothing new there) but I saw an email
so I email this guy, hoping he still checks this email, and what do you know? HE EMAILED BACK.
Hello,
As you have mentioned yourself, It was a long time ago and I don't remember much. Plus, I never did try to convert any of the models back. I am 99% positive that it is possible - you'll need the right tool-set though. I am not sure what tools are available for "Combat Arms", but as far as I remember there is an extensive toolkit for NOLF2 (which uses the same engine, more or less):
You'll need the game itself (NOLF2) to install the toolkit though (which can be a problem). Also, you may want to take a look at these forums (NOLF 2 - Mods & DEdit - The Glue Factory
) and search for anything related to LTA\LTB tools\plugins.
Hope that helps.
Sorry for the outside links. I'm sure you want them a lot more than you don't want them.
