Edit question vog_25; vog_25p; (STALKER: Shadow of Chernobyl)

Hello everyone ! I want to fix the grenades for the grenade, but I can't find their files. I want to make them bang like f1, or even better. In general, do they have separate files, or are they inscribed somewhere? Or maybe you can just attribute the F1 grenade to the grenade launcher. in addition to vog25 and vog25p, it would be cool !!! ))) Although f1 probably cannot be assigned to the grenade launcher, it is in the category of weapons, and VOGs in the category of cartridges.
