Get objects in a model

Hey guys, I am making kill parts with a single script, how could I get the objects inside these models which are in folders,

GetChildren() only gets the models, how can I get the children of the models for each model as well?

You just call :GetChildren() on the models

Alternatively you can just do Killers:GetDescendants() and use an if statement to check if the descendant is a BasePart

So I would have to call GetChildren() for each model?

for i, model in ipairs(Killers:GetChildren()) do
    for i, part in ipairs(model:GetChildren()) do
        -- do stuff with parts inside models
    end
end
