Knife changer not working

I did update csgoclass id and replaced this if (sWeapon.find("models/weapons", 0) != std::string::npos)
continue;

here is a message i get from console:
you are getting this error: Failed to set custom material for 'karam', no matching material name found on model models/weapons/v_knife_default_t.mdl

I think youre not the only one...

applyAAAhooks(); in DLLMain.cpp

then paste it at end of Antiantiaim

void ApplyAAAHooks()
{
ClientClass *pClass = Interfaces::Client->GetAllClasses();
while (pClass)
{
const char *pszName = pClass->m_pRecvTable->m_pNetTableName;
if (!strcmp(pszName, "DT_CSPlayer"))
{
for (int i = 0; i < pClass->m_pRecvTable->m_nProps; i++)
{
RecvProp *pProp = &(pClass->m_pRecvTable->m_pProps[i]);
const char *name = pProp->m_pVarName;

// Pitch Fix
if (!strcmp(name, "m_angEyeAngles[0]"))
{
pProp->m_ProxyFn = FixX;
}

// Yaw Fix
if (!strcmp(name, "m_angEyeAngles[1]"))
{
Utilities::Log("Yaw Fix Applied");
pProp->m_ProxyFn = FixY;
}
}
}
else if (!strcmp(pszName, "DT_BaseViewModel"))
{
for (int i = 0; i < pClass->m_pRecvTable->m_nProps; i++)
{
RecvProp *pProp = &(pClass->m_pRecvTable->m_pProps[i]);
const char *name = pProp->m_pVarName;

// Knives
if (!strcmp(name, "m_nModelIndex"))
{
oRecvnModelIndex = (RecvVarProxyFn)pProp->m_ProxyFn;
pProp->m_ProxyFn = Hooked_RecvProxy_Viewmodel;
}
}
}
pClass = pClass->m_pNext;
}
}
