How to make a script that will make all parts of a model be transparent ?

Hello Everyone , I have a problem i want to make a script that will make all parts of my model Named "TransparentWindows" be Transparent when i push a button. The button part is not problem but how do i get all the parts of a model in a script ?

Thank you Forward.

(Sorry there isnt a script because i coudlnt manage to make one)

You can get all child inside the model using :GetChildren() function, this will return a table with all the children in it , you can then put it inside a variable example :

local childs = workspace.Model:GetChildren()

and then you can loop through them using a for loop example :

local childs = workspace.Model:GetChildren()
for i, v in pairs(childs) do
	print(v.Name)
end

then you can check if the child is a part using if example :

local childs = workspace.Model:GetChildren()
for i, v in pairs(childs) do
	if v:IsA("BasePart") then
		print(v.. "Is a part!")
	end
end
