What can fix character animations not visible to others?

Hello!

This is my first time asking a question on here, so bare with me..;

I currently have an issue with a 'pose tool' that I have for my game. I recently updated my entire game to be FilteringEnabled compatible and everything works fine, except for the pose tool, sort of.

It works on your screen perfectly as intended, but it is not seen by others around you. For example, I could have an arm up on my screen, but on others, it's not visible at all.

Here is the code from one of the tools:

bin = script.Parent
Tool = script.Parent;
function getjoint() 
player = bin.Parent
char = player
if char ~= nil then 
torso = char:FindFirstChild("Torso") 
if torso~= nil then 
joint = torso:FindFirstChild("Left Shoulder") 
if joint~=nil then 
return joint 
end 
end 
end 
return nil 
end 

function getarm() 
player = bin.Parent
char = player
if torso~= nil then 
arm = char:FindFirstChild("Left Arm") 
if arm~=nil then 
return arm 
end 
end 
return nil 
end 

function pointarmto(t, a, p, c0, c1) 
mid = (t.CFrame*CFrame.new(c0)).p --offset position 
dir = (mid - p).unit 
rot = CFrame.fromEulerAnglesXYZ(math.pi/2, 0, 0) 
rightangle = CFrame.fromEulerAnglesXYZ(0, 0, math.pi) 
off = CFrame.new(c1) 
a.CFrame = CFrame.new(mid, mid+dir)*rot*off*rightangle 
end 

function Bob(mouse)
    while sel do
        wait(0.01)
joint = getjoint() 
local c0 = nil 
local c1 = nil 
if joint~= nil then 
c0 = joint.C0.p -- center of arm 
c1 = joint.C1.p 
arm = getarm() 
arm.Anchored = true 
torso = joint.Part0 
joint.Part1 = nil -- detach arm 
pointing = true 
point = mouse.Hit.p 
pointarmto(torso, arm, point, c0, c1) 
end 
end
end


function FreddyBobson(mouse)
    sel = true
Bob(mouse)
end

script.Parent.Equipped:connect(FreddyBobson)
    sel = true
Bob()

function Desel(mouse)
joint = getjoint() 
arm = getarm() 
joint.Part1 = arm 
arm.Anchored = false 
sel = false
end

script.Parent.Deequipped:connect(Desel)

What am I missing? Should RemoteEvents/Functions be involved?
