repost because i never got an answer

i cant anymore bro this is driving me fucking crazy i tried learning this months ago to no avail
tried again today and it just WONT WORK!!!!
i have this stupid ass model where both of those gray parts are welded to the red part via weldconstraint (the red part is set as the model's primarypart)

i have a clickdetector which tweens the primarypart's cframe to go upwards but GUESS WHAT!! ONLY THE PRIMARYPART MOVES AND THE OTHER PARTS STAY STATIC!!!!!!! AND THEYRE UNANCHORED!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
ive also tried with normal welds in case weldconstraints were the issue but that didnt work

clickdetector script:

local center = workspace.dumbstupidihateyou.PrimaryPart
local ts = game:GetService("TweenService")

script.Parent.MouseClick:Connect(function()
    ts:Create(center, TweenInfo.new(3, Enum.EasingStyle.Linear), {CFrame = center.CFrame + Vector3.new(0, 5, 0)}):Play()
end)

tldr: tweening model wont work even though welds are set up correctly, primarypart anchored other parts unanchored

You do know that tweens only work on the selected part right?

You can only tween every part individually and play them at the same time since you can't tween a model

[ocean crescent]

ive seen multiple instances where people have tweened models by welding everything
this only seems to happen for me for whatever reason

if you had to tween each part individually thatd be wildly unoptimized

[flint pond]

Hmmm hold on

[loud swallow]

I think you have to use model:MoveTo(<vector3 goes here>)

It moves the primary part to the position and the rest move along

[ocean crescent]

yeah but moveto is instant

[flint pond]

Hu

1 sec

[ocean crescent]

and you cant tween a moveto because tweens take properties in the third parameter

[loud swallow]

Right

Idk how then

[flint pond]

Lol

Weds dont work btw

** You are now Level 8! **

[ocean crescent]

they do, ive seen multiple devforum posts and videos showcasing welds to tween models so thats why im confused why it doesnt work for me

the videos show it working flawlessly then i try and it just. doesnt work

[flint pond]

Gpt saves the day again!

local model = workspace:WaitForChild("dumbstupidihateyou")
local ts = game:GetService("TweenService")

-- Create a "fake" ValueObject to tween
local fakeValue = Instance.new("CFrameValue")
fakeValue.Value = model:GetPrimaryPartCFrame()

-- Target CFrame (5 studs up)
local goalCFrame = fakeValue.Value + Vector3.new(0, 5, 0)

local tween = ts:Create(fakeValue, TweenInfo.new(3, Enum.EasingStyle.Linear), {Value = goalCFrame})

-- On each frame, update the model position
fakeValue:GetPropertyChangedSignal("Value"):Connect(function()
model:SetPrimaryPartCFrame(fakeValue.Value)
end)

script.Parent.MouseClick:Connect(function()
tween:Play()
end)

Heres an example

dude

[flint pond]

Im not fully sure why this works tho so imma do some research
