How to add viewmodel changer to osiris

[tonti666]

Not sure how to add this to hooks

1. interfaces::console->get_convar("viewmodel_fov")->callbacks.SetSize(false);
2. interfaces::console->get_convar("viewmodel_offset_x")->callbacks.SetSize(false);
3. interfaces::console->get_convar("viewmodel_offset_y")->callbacks.SetSize(false);
4. interfaces::console->get_convar("viewmodel_offset_z")->callbacks.SetSize(false);

because there is no setsize in the cheat, only setvalue and that doesnt work
