Find all parts on a ray

function RecurseRaycast(qRay, IgnoreList) -- IgnoreList is a table of objects to ignore.
    local Returns = {};
    local OriginalLength = qRay.Direction.magnitude;
    local Raycast;
    function Raycast(qRay, IgnoreList)
        local Hit, Pos, Normal = workspace:FindPartOnRayWithIgnoreList(qRay, IgnoreList);
        if (Hit) then
            table.insert(Returns, {Hit,Pos,Normal});
            table.insert(IgnoreList, Hit);
            local NewRay = Ray.new(qRay.Origin, qRay.Direction.unit * (OriginalLength - (qRay.Origin - Pos).magnitude ))
            return Raycast(NewRay, IgnoreList)
        end
    end
    Raycast(qRay, IgnoreList);
    return Returns;
end

-- Example of usage

local Returns = RecurseRaycast(
    Ray.new(workspace.RayTester.Position, workspace.RayTester.CFrame.lookVector * 500),
    {workspace.RayTester}
)

if (#Returns == 0) then
    print("Ray hit nothing.");
else
    for i,v in ipairs(Returns) do
        print(unpack(v))
    end
end
