Creating sideways gravity that works for ragdolls

I’m trying to create gravity that doesn’t go in the negative Y axis (in this specific case, it’d be the positive Z axis instead), however, a single LinearVelocity (or one paired with a VectorForce) would not work, as the character being affected isn’t a (relatively) rigid object, but instead a ragdoll.

Currently, I give each of its limbs a VF and a LV, which somewhat simulates gravity correctly, but when I throw the ragdoll on some stairs, it fails to fall “down” the stairs as smoothly as it would if I was using roblox’s inbuilt gravity.

(“Falling” up the stairs using my artificial gravity)

(Falling down the stairs using default roblox gravity)

Code which applies the gravity:

for _, v in character:GetChildren() do
		if v:IsA("BasePart") then
			--if v.CanCollide == true then
				local LV = Instance.new("LinearVelocity")
				local VF = Instance.new("VectorForce")
				local attach = Instance.new("Attachment")
				VF.Parent = v
				attach.Parent = v
				LV.Parent = v
				VF.Attachment0 = attach
				LV.Attachment0 = attach
				VF.RelativeTo = Enum.ActuatorRelativeTo.World
				LV.RelativeTo = Enum.ActuatorRelativeTo.World
				LV.ForceLimitMode = Enum.ForceLimitMode.PerAxis
				LV.MaxAxesForce = Vector3.new(0, 10000, 0)
				LV.VectorVelocity = Vector3.new(0, 0, 0)
				VF.Force = Vector3.new(0, 0, 5*196.2 * v:GetMass())
			--else
				--v.Massless = true
			--	continue
			--end
		end
	end

(if it helps, the humanoid of the character is in the Physics state when it is ragdolled, and the server is the network owner of the character)
