Modding VC

[Griff379]

hey guys, im new to this whole GTA VC modding stuff. i have modded 18wos PTTM for a LONG time, so i am familiar with modding in general, but getting the DFF and TXD's to show up aint working out so good. i converted a .PSM (pttm) file, with all the correct extensions and i renamed all the parts for the doors, hood, bumpers, chassis, ETC, and the only thing that shows up INgame is the windshied and glass. i know the DFF is correct, i've double checked it several times. but i dont know how to map things in DFF format. the truck is already mapped to one .BMP, but how do i get in to a TXD/ playable format?

any help is appreciated, Griff379.
