Welded object is affecting the movement of the player

[SGP_PRO (SGPlayz)]

Hi so basically im welding a model to the player, however it seems like its affecting the movement of the player, kinda like giving the player a backward force.

Here is the script

    local Ventus = SkillModelFolder.WindModel:Clone()
	Ventus.Parent = workspace
	Ventus.CFrame = plr.Character.HumanoidRootPart.CFrame * CFrame.new(0,0,-7) * CFrame.Angles(0,math.rad(180),0)
	
	local weld = Instance.new("Weld")
	weld.C0 = CFrame.new(0,0,-7) * CFrame.Angles(0,math.rad(180),0)
	weld.Parent = Ventus
	weld.Part1 = Ventus
	weld.Part0 = plr.Character.HumanoidRootPart

The wind model have density of 0 (clamped to 0.0001), can collide false, and its not anchored. Any idea on why this happens?

Make the contents of the model Massless to prevent it from affecting the character’s center of mass.
