Rpg/law to Knife Model Swap

aw okay, and i have search and i've looked at all the tutorials, one the tut only does Ar to another ar, so after i rename i get lost on where inject my rename files launchers or knife, that being said the one i found searching only gives me the rez version which is no help since i cant use it i need the .ltb files--> the rename ones ) and also does change the looks of nade to knife also makes it faster? the throwing and if so where would i inject since im cross modal swaping a meelee rez and an launcher, throwing rez. , if u can just tell me where to inject.. thanks

its kind of common sense. That AR to AR is the same thing, just extract all the rez files you need to extract, rename the knife file to the rpg, and inject

i dont have ca, i just know the engine well from having it and modding in the past

where do i inject tho
edit, i mean like if its froom ar to ar u inject in the GUNS_M_PV_AR
but if its from like rpg to knife where do u inject?>
