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
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.
The lookVectors are printing properly, however despite the lookVector changing, the head of the second player stays in the same position, which hopefully helps narrow down the location of issue?
I also noticed a strange animation jitter with the functioning head, which I think is something I can handle later and very likely related to (but not caused by) this other issue.
Information dump since I have yet to get a response. I had a very long conversation on Discord with another scripter and they ultimately couldn’t help me. This is very important to me. I’ve been trying to figure this out for days and the lack of progress is causing extreme anxiety and ruining my motivation for the project as a whole.
Part transparency for head-turning has been turned to 0 to display the difference between Player 1 and Player 2. Once again had to post the clip on YouTube because of size limitations: https://www.youtube.com/watch?v=2tfcBaeeL64
Some screenshots of output errors that likely aren’t the cause (I think the issue is in the CharacterIKs script)

I will definitely try to fix the errors ASAP for sure. I also went and sent a message to the person who originally made the tutorial and adjusted script (5uphi) and they said they’d take a look at it. Hopefully I can fix it soon haha
I don’t know how to adjust the script to make way for such a change.
While talking to 5uphi I adjusted some scripts, this post has details on how so.
This is what it looks like right now:
The script adjusted for these changes was the CharacterIKs script, however it is still having issues on the second client as seen on the video linked.
local runService = game:GetService("RunService")
local parts = {}
local iks = {}
local function CharacterAdded(character)
local ik = Instance.new("IKControl")
ik.Type = Enum.IKControlType.LookAt
ik.ChainRoot = character:WaitForChild("Neck2")
ik.EndEffector = character:WaitForChild("Head")
ik.Target = parts[game.Players:GetPlayerFromCharacter(character)]
ik.Parent = character.Humanoid
iks[character] = ik
character.Humanoid.Died:Wait() ik:Destroy()
end
local function CharacterRemoving(character)
iks[character] = nil
end
local function PlayerAdded(player)
local part = Instance.new("Part")

end

parts[player] = nil
end

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:WaitForChild("Head").Position - player:GetAttribute("LookVector") * 10
end
end)
Hey there! After some testing, I think I’ve figured out the problem. I downloaded the file “Inverse_Kinematics_Dynamic_Weight.rbxl,” and it seems that when it’s in use, the other player’s character consistently looks down. The weird part is that it also shows on their screen that other players are looking down too.
I tried removing line 16 from the localscript “CharacterIKs,” and everything worked fine after that. I’ll share the Roblox place link below this message. Hope this helps with your urgent issue.
The reason for this issue is quite straightforward. By removing line 16, we address a problem with the “Character Added” function. This function essentially gets stuck, waiting for the character to die before moving on to the next set of codes. Consequently, the “RenderStepped” function doesn’t run as intended because it’s essentially halted on the “Character Added” function from line 16.
If you were to insert a print statement within the “RenderStepped” function, you’d notice that it consistently prints for one player, while for another player, it doesn’t. In essence, removing line 16 resolves this bottleneck and ensures the smooth execution of subsequent code, mitigating the issue you encountered.
To make sure that the “ik” variable is destroyed when the character dies, it’s better to use a humanoid.died function instead of waiting for it to happen.
Feel free to reach out if you have any more questions or need further clarification.
OH MY GOD IT WORKS
I seriously couldn’t figure out the issue by myself but you really saved me and my workflow. I made a few changes to your script (such as the onDied like you suggested) and tested it on a proper server with two different accounts and the head-turning is perfect. You’re my hero for this, thank you so much!!!
Of course!
and to any poor soul searching the internet for this oddly specific solution, this is the final script I ended up with. It probably isn’t the best, but it does the trick!
local runService = game:GetService("RunService")
local parts = {}
local iks = {}
local function CharacterAdded(character)
local ik = Instance.new("IKControl")
ik.Type = Enum.IKControlType.LookAt
ik.ChainRoot = character:WaitForChild("Neck2")
ik.EndEffector = character:WaitForChild("Head")
ik.Target = parts[game.Players:GetPlayerFromCharacter(character)]
ik.Parent = character.Humanoid
iks[character] = ik
local function onDied()
ik:Destroy()
end
end
local function CharacterRemoving(character)
iks[character] = nil
end
local function PlayerAdded(player)
local part = Instance.new("Part")
part.Anchored = true
part.CanCollide = false
part.CanQuery = false
part.CanTouch = false
part.Transparency = 0
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:WaitForChild("Head").Position - player:GetAttribute("LookVector") * 10
end
end)
QUICK UPDATE TO ANYONE FOLLOWING THIS:
The head-turning will temporarily break if other players do not morph into the proper model. So I highly suggest forcing the player to automatically morph when they join the game, or figuring out how to fix that. (If you do figure it out, share those deets with me lol)
