hand offset?

Hey! I want to add a nohand feature to my hack. Its external. I searched on some forum, and i saw everyone useing some "ArmOffset" and viewmodel offset. But i cant find it in hazedumper :/ and i found an offset, i think its old af 0x38E3 tried to find the new on this but i cant :/ please any help. thanks!

DWORD m_nModelIndex = 0x0254;

Set it to an invalid value (0 / etc..) You can also do pretty funny stuffs like changing the model of grenades, also it's the way to make an external knifechanger, type sv_precacheinfo into console

Usage:
Mem->Write<int>(LocalPlayer->GetEntityBasePtr() + Netvars->m_nModelIndex, 0);
