How do I make my stand not have collide?

local PS = game:GetService("PhysicsService")
PS:CreateCollisionGroup("Player")
PS:CollisionGroupSetCollidable("Player","Player",false)
 
game.Players.PlayerAdded:Connect(function(Player)
    Player.CharacterAdded:Connect(function(Character)
        Character:WaitForChild("HumanoidRootPart")
        Character:WaitForChild("Head")
        Character:WaitForChild("Humanoid")
        for i,v in pairs(Character:GetChildren()) do
            if v:IsA("BasePart") then
                PS:SetPartCollisionGroup(v,"Player")
            end
        end
    end)
end)

All you really need to do is add a recursive function to get all the baseparts in a model and to make them not collide with the "Player" collision group.

You just need to pass in your bodyguard and stand models into it and it should work.

local PS = game:GetService("PhysicsService")
PS:CreateCollisionGroup("Player")
PS:CollisionGroupSetCollidable("Player","Player",false)

local function noCollide(model)
	for _, v in pairs(model:GetChildren()) do
		if (v:IsA("BasePart")) then
			PS:SetPartCollisionGroup(v,"Player")
		end
		
		noCollide(v) --//To go through the entire model
	end
end

game.Players.PlayerAdded:Connect(function(Player)
    Player.CharacterAdded:Connect(function(Character)
        Character:WaitForChild("HumanoidRootPart")
        Character:WaitForChild("Head")
        Character:WaitForChild("Humanoid")
        
		noCollide(Character)
    end)
end)

Example usage for your problem:

local bodyGuard = (Bodyguard Model)
local stand = (Stand Model)

noCollide(bodyGuard)
noCollide(stand)
