Infinitely scrolling background help

Help and Feedback Scripting Support
#1

The code below is used to move the front segment of an infinitely scrolling background to the back. The part where the Welds are disabled is undesirable for obvious reasons, yet if I don’t do that, the PivotTo() function will bring the entire background backwards. Is there another way to do this? I don’t want to use MoveTo()

local function movetoBack()
	for _, v in pairs(script.Parent:GetDescendants())do
		if v:IsA("WeldConstraint") then
			v.Enabled = false
		end
	end
	currentfront:PivotTo(currentlast.BACK:GetPivot())
	for _, q in pairs(script.Parent:GetDescendants())do
		if q:IsA("WeldConstraint") then
			q.Enabled = true
		end
	end
	local backid = currentfront.Name
	currentlast = script.Parent[backid]
	local frontid = tostring(tonumber(currentfront.Name)+1)
	if frontid == "6" then
		frontid = "1"
	end
	currentfront = script.Parent[frontid]
end
