Allow Character Movement while Welding Charatcer's Parts

Hello developers! :wave:

I’m currently attempting to drive CFrames of a Character’s Parts (Head, Left Arm, Right Arm, LeftHand, RightHand, etc.) by Constraining all the part’s of a Character to another duplicate dummy’s parts using RigidConstraints.

My current issue is that by using Constraints to attach a character’s parts to the dummy’s parts, “freezes” the character, making the character unable to move. I’ve attempted using a Motor6D instead, which does move parts while also running animations, but that isn’t my goal. I’ve also attempted Constraining all parts but the HumanoidRootPart, and that’ll just fling the player into the atmosphere (as expected).

Here is my current function that Constrains the Character’s Parts to the Dummy’s Parts

Where character is a player’s Character, newdummy is the Dummy Rig that goes along with the Character, part is a descendant of the Character, and dummypart is a descendant of the Dummy rig.

function ConstrainModel(character, newdummy)
	for _, part in character:GetChildren() do
		if part:IsA("BasePart") then
			if newdummy:FindFirstChild(part.Name) ~= nil then
				local dummypart = newdummy:FindFirstChild(part.Name)
				dummypart:PivotTo(part.CFrame)
				local att0 = Instance.new('Attachment')
				att0.Parent = part
				local att1 = Instance.new('Attachment')
				att1.Parent = dummypart
				local RigidConstraint = Instance.new('RigidConstraint')
				RigidConstraint.Attachment0 = att0
				RigidConstraint.Attachment1 = att1
				RigidConstraint.Parent = dummypart
				dummypart.Anchored = true
			else
				warn("Could not find part "..part.Name.." inside of the Dummy Avatar!")
			end
		end
	end
end

And for extra context, the Character’s Parts are manipulated by driving the Dummy’s CFrames with the PivotTo function.
