This is the first problem I've encountered in years, and uhm I don't exactly know what's wrong here, am I blind that I can't see the problem or is it just wrong like this (I have one mod I made on this writing and it's working fine and this part of the code isn't for some reason).

So let's go straight to the problem. The problem is that when I choose knife model I wanna set on me (in this case Test), it doesn't work. I tried to see, is the function even working at all (Set / VIP Set) and it seems it works, so I guess the problem is in SetKnife or that I didn't add something very important which it seems I can't guess what it is. So yeah in short setting model on a knife isn't working.

public SetKnife(id, knife)
{
	new clip, ammo, weapon = get_user_weapon(id, clip, ammo);
			
	if(weapon != CSW_KNIFE)
		return;
		
	knife_model[id] = knife;
		
	new v_Model[56];
	new p_Model[56];
	
	format(v_Model, 55, knifeData[knife][vModel]);
	format(p_Model, 55, knifeData[knife][pModel]);

	set_pev(id, pev_viewmodel2, v_Model)
	set_pev(id, pev_weaponmodel2, p_Model)
}

public CurWeapon(id)
{
	SetKnife(id, knife_model[id]);
}

Btw I was doing some tests and I wrote this literally like 30m ago and it surprised me that it isn't working whatever I try, so that's why I'm curious what is the problem here. Would mean a lot if someone could explain
