Hello everyone, maybe not on the topic, but for some reason the mods for weapons in GTA do not work for me, I replace them in open 4, like all the rules, I go to the file as there is a ytd model out of fashion, but the game has a standard vanilla skin, what not to do I know, it seems that no one had any problems with this, I will spawn the weapon from the trainer, thanks in advance, sorry for my English
