EDIT: Marked title as “URGENT” because progress cannot be made on the game (more specifically, the game cannot be played multiplayer) without resolving this.

Try using a remote event to change SetAttribute (“LookVector”) in your local Look script.

I don’t understand. Sorry, I’m not well versed in Luascript and followed a string of tutorials to get to this point. 
I searched up the documentation on remote events and it doesn’t look all too different from what the script already contains.
Sorry for the late response, I just noticed you were setting an attribute on line 7 of your local script and you need to use a server script to set attributes.

Check out my following scripts to see the change I made. It probably wasn’t the best since I don’t fully understand how to edit such an advanced script. All the change did was make the head-turning a little more laggy/jittery, and still has the second player to join the game experience broken head turning.
I tried putting the full contents of the local “Look” script into the server “Look” script and it resulted in… this
Local “Look” script
local event = game.ReplicatedStorage.Look
local lookVector = Vector3.zero
local eventTime = -math.huge
local scheduleEvent = false
workspace.CurrentCamera:GetPropertyChangedSignal("CFrame"):Connect(function()
--game.Players.LocalPlayer:SetAttribute("LookVector", workspace.CurrentCamera.CFrame.LookVector)
if scheduleEvent == true then return end
if workspace.CurrentCamera.CFrame.LookVector:Dot(lookVector) > 0.99 then return end
local deltaTime = time() - eventTime
if deltaTime > 0.1 then
eventTime = time()
lookVector = workspace.CurrentCamera.CFrame.LookVector
event:FireServer(lookVector)
else
scheduleEvent = true
task.wait(0.1 - deltaTime)
scheduleEvent = false
eventTime = time()
lookVector = workspace.CurrentCamera.CFrame.LookVector
event:FireServer(lookVector)
end
end)
Server “Look” script
game.Players.PlayerAdded:Connect(function(player)
player:SetAttribute("LookVector", Vector3.zero)
end)
game.ReplicatedStorage.Look.OnServerEvent:Connect(function(player, lookVector)
player:SetAttribute("LookVector", lookVector.Unit)
end)
workspace.CurrentCamera:GetPropertyChangedSignal("CFrame"):Connect(function()
game.Players.LocalPlayer:SetAttribute("LookVector", workspace.CurrentCamera.CFrame.LookVector)
end)
Also here’s “CharacterIKs” localscript which is related to the Look scripts but likely not this issue in particular.
local function PlayerAdded(player)
local part = Instance.new("Part")
part.Anchored = true
part.CanCollide = false
part.CanQuery = false
part.CanTouch = false
part.Transparency = 1
part.Parent = workspace
parts[player] = part
if player.Character ~= nil then CharacterAdded(player.Character) end
player.CharacterAdded:Connect(CharacterAdded)
player.CharacterRemoving:Connect(CharacterRemoving)
end
local function PlayerRemoving(player)
parts[player]:Destroy()
parts[player] = nil
end
for i, player in game.Players:GetPlayers() do PlayerAdded(player) end
game.Players.PlayerAdded:Connect(PlayerAdded)
game.Players.PlayerRemoving:Connect(PlayerRemoving)
runService.RenderStepped:Connect(function(deltaTime)
for player, part in parts do
if player.Character == nil then continue end
local ik = iks[player.Character]
if ik ~= nil then ik.Weight = 1 + player:GetAttribute("LookVector"):Dot(player.Character.HumanoidRootPart.CFrame.LookVector) end
part.Position = player.Character.Head.Position - player:GetAttribute("LookVector") * 10
end
end)```Just a question, why do you need server side script?

I was following a tutorial that said it was required and I’m pretty sure it’s so other players can see the head turning as well?
This problem has not been solved yet!
Try just two scripts. Make changes on sever so everyone can see.

ik.Target = parts[game.Players:GetPlayerFromCharacter(character)]
ik.Parent = character.Humanoid
iks[character] = ik
character.Humanoid.Died:Wait() ik:Destroy()
end

No, client has NetworkOwnership over their character. So you don’t need Server script

please help. i have no clue what youre trying to tell me.
I’m not entirely sure what you’re trying to ask me. The rig is not available to the public because I made it myself and don’t want to lose it. However I’ll try to respond to what you’re asking?
The player applies the character by clicking a morph menu, which runs a local script
local ReplicatedStorage = game:GetService("ReplicatedStorage")
script.Parent.MouseButton1Click:Connect(function()
ReplicatedStorage.MorphEvent:FireServer()
end)
and connects to this portion of a very long server-side character customization script, basically destroying the old player character and replacing it with the new model.
-- MORPH --
local Players = game:GetService("Players")
game.Players.PlayerAdded:Connect(function(plr)
local player = plr
game.ReplicatedStorage.MorphEvent.OnServerEvent:connect(function(plr)
local oldCharacter = player.Character
local newCharacter = FelineParent.Feline:Clone()
newCharacter.HumanoidRootPart.Anchored = false
newCharacter:SetPrimaryPartCFrame(oldCharacter.PrimaryPart.CFrame)
player.Character = newCharacter
newCharacter.Parent = workspace
end)
end)
and if you’re asking how the model connects to the rig, the HumanoidRootPart connects to Torso1
Besides that, I’m not sure what you’re trying to ask me
I forgot to change the ik.ChainRoot back to neck2 I had to change it to work with just my character as I don’t have the cat rig.
ik.ChainRoot = character:WaitForChild("Neck2")

I’m sure I changed that on my end when I tried out your script, otherwise the heads wouldn’t turn at all for any players to join the game.
Note that the head-turning is functioning fine! But only for the first player to join the game. Everyone else’s head-turning won’t work. So when you test it, it needs to be with another player.
If you guys need further context to help understand the problem, here is some additional information.
I followed this tutorial by Suphi Kaner. It had some issues and I had to join the Discord to get the proper script, which can be found in this place file he provided for free: Inverse_Kinematics_Dynamic_Weight.rbxl (57.9 KB)
On my end I applied some of the math in reverse, since my model needed to move in opposition to the camera rather than following it, so if you’re having troubles applying it to your model / the normal Roblox avatar, please check the tutorial and compare it to my script. The change should be as simple as changing a “-” back to a “+”.
And again to clarify, the issue is occurring with two players, not one. When troubleshooting your solutions, you need to test it with another player on a Roblox server to see if it’s recreating itself.
Let me know if there’s more I need to clarify.
I added two print commands to your original server script.
They print as expected for 2 players.
game.Players.PlayerAdded:Connect(function(player)
print("Player Added: look vector")
player:SetAttribute("LookVector", Vector3.zero)
end)
game.ReplicatedStorage.Look.OnServerEvent:Connect(function(player, lookVector)
print(player, "look vector", lookVector)
player:SetAttribute("LookVector", lookVector.Unit)
end)
--workspace.CurrentCamera:GetPropertyChangedSignal("CFrame"):Connect(function()
-- print("server camera")
-- game.Players.LocalPlayer:SetAttribute("LookVector", workspace.CurrentCamera.CFrame.LookVector)
--end)
Try them and see if they work as expected.
If not, then add print commands in other places until you figure out where the values are not being sent or received.
Also, select the lookVector in the property window for each player and see if it is really being updated by the scripts.
