How do I hide the vanilla player model?

There are two different solutions for both the prewrite and rewrite. See below for both versions.

Prewrite

for key, value in pairs(vanilla_model) do
	value.setEnabled(false)    
end

Rewrite

To hide everything in the player model (including armor and held items), do the following:

vanilla_model.ALL:setVisible(false)

To hide only the limbs, you will have to use a different set of lines.

vanilla_model.INNER_LAYER:setVisible(false)
vanilla_model.OUTER_LAYER:setVisible(false)
