I wanted to create a viewModel arms for my gun system, but I ran into trouble because they wouldn’t follow the camera even if I tried setting the CFrame of its main part to the CFrame of the camera. Nevertheless, cloning the head and making it function as the primary part of that model did work (added weld), but it made the player move and fly with the camera’s movements. I’ve now added the right arm as the primarypart as it is the arm equipped with tool.

What is the best solution for this problem? I always appreciate your assistance! Thank you so much.

Script with the Head added:

	local Head = LocalPlayer.Character:FindFirstChild("Head"):Clone()
	Head.Name = "Head"
	Head.Transparency = 0
	Head.CanCollide = false
	Head.Parent = Arms
	
	local w = Instance.new("Weld")
	w.Part0 = Head
	w.Part1 = LocalPlayer.Character:FindFirstChild("Head")
	w.C0 = CFrame.new()
	w.C1 = CFrame.new()
	w.Parent = Head	
	Head.Parent = Arms
	
	LocalPlayer.CameraMaxZoomDistance = 0
	LocalPlayer.CameraMinZoomDistance = 0
-- ... function end here ...
-- ... etc ... (other codes)

RunService.RenderStepped:Connect(function()
	for i, v in pairs(CurrentCamera:GetChildren()) do
		if v:IsA("Model") then
			v:FindFirstChild("Head").CFrame = CurrentCamera.CFrame
		end
	end
end)

The following happens when I add Head: robloxapp-20240120-1438121.wmv (2.8 MB)

I also know that this is caused due to the weld, but again without that weld it doesn’t work at all. So, I just need a solution for this problem.

I think the problem is the collisions. Instead of setting the cloned body parts’ CanCollide property to false, change their CollisionGroups to a group that does not collide with anything instead. I’m not sure if this would work but whenever I make viewmodels, I always use CollisionGroups instead of CanCollide. I hope this helps!

Also, if you are going to make viewmodels, just create a pre-made viewmodel and then clone a tool that is equipped and place it in the viewmodel. Make sure to manually add a grip joint so it will be attached to the viewmodel rig. To animate the viewmodel, just copy the Transform property of every Motor6D joint in the character and set it as the Transform of the Motor6D in the viewmodel. This is what I usually do when making viewmodels so I hope this helps aswell!
