RNG Aura model follow player

[orchid sparrow]

This is bugged, I want the black hole to follow me above my head, I welded all the parts to PrimatyPart with a plugin but when I move it bugs and sends me anywhere.
part of script : elseif v:IsA("Model") then
local modelClone = v:Clone()
modelClone:SetAttribute("DestroyOnChange", true)

            local bodyPartName = modelClone:GetAttribute("BodyPart") or "Torso"
            local targetPart = player.Character:FindFirstChild(bodyPartName)

            if targetPart and modelClone.PrimaryPart then
                modelClone.Parent = player.Character

                -- Décalage de 3 studs au-dessus du BodyPart
                local offset = CFrame.new(0, 10, 0)
                modelClone:SetPrimaryPartCFrame(targetPart.CFrame * offset)

                local weld = Instance.new("WeldConstraint")
                weld.Part0 = targetPart
                weld.Part1 = modelClone.PrimaryPart
                weld.Parent = modelClone.PrimaryPart
            end

make sure no part in blackhole can collide, also make it massless so it doesnt put force on player

Prob collision problems
