i have exported minigun model and view hand model but i cant find any files of minigun in cod4/raw/weapons/sp...can someone help me or get me scripts for it .HELP!!!!!

you have to convert the weaponfile yourself if you open asset manager open the gdt weaponsettings and find the minigun now export it ...
But it won't until you have animations for it

also you may need to convert the anims as well, depending if your mod tool like you or not
