Can't Tween Orientation of Welded Model

Recently I was trying to tween a model by using the primary part then unanchor and weld every part to that primary part.
The problem is that the primary part rotates but the others stay still in the air or move very slowly.

image I used WeldConstraint for it


local tween = game:GetService("TweenService")

local TI =, Enum.EasingStyle.Circular, Enum.EasingDirection.InOut, math.huge, true)

script.Parent["Oreo Death Thingy"].Touched:Connect(function(hit)
if hit.Parent:FindFirstChild("Humanoid") then

tween:Create(script.Parent.SpiningPart, TI, {Orientation =,0,0)}):Play()

Have you anchored the Primary Part?

Yes, of course, I anchored it.

You sure all the weld’s are configured correctly? Maybe try using welds instead of Weld Constraints

Also, maybe you can try tweening the CFrame rotation instead of orientation.

I can’t use welds it changes the position of part. I will try to tween the CFrame then.

Hey according to this,
Weld Constraints are disabled temporarily while this property is changed.
Using CFrame should fix the problem
