Did I do something wrong?
I tried changing models from the AK47 to the Scar Light but no avail. I changed all the files they had together and I injected them into GUNS_M_PV_AR but it does not change anything in the game when I use the AK. I changed the CM_HND_SP_DF_ of the AK to the Scar L, the PVMLA_ of the AK to Scar, PVMLA_W_ of the AK to Scar, and the PVMSH_ of the AK to Scar, injected them but nothing. So did I do something wrong?
probably not. trying to mod anything like that is a pain in the ass.
if you've done a million conversions... then actually opened those files up in a program like 3DS Max. You'd see that some of the files arn't just weapons, but they also have arms, and stuff. so you probably just changed the name of the wrong file.
you should try to get 3DS Max, then see what all those look like for yourself. then, you might be able to mod something in that way.
