This has been a recurring problem for me. I wish to convert models from this game for a personal project of mine. Apparently tools exist such as 3DSmax plugins, but they are far outdated. There's also a model viewer, but exporting from it loses UV information and has a lot of glitches. I was hoping someone could put together something to convert these properly.
