Lerp being really jittery


i finally achieved the effect i wanted for my framework with the viewmodel avoiding walls, but its acting really jittery

‘startOfOBJ’ is an attachment placed in the hrp positioned right by the weapons barrel

		if vm and wep then

		local result = workspace:Raycast(vm:WaitForChild("HumanoidRootPart"):WaitForChild("startOfOBJ").WorldPosition,vm:WaitForChild("HumanoidRootPart"):WaitForChild("startOfOBJ").WorldCFrame.LookVector * wepModule.basicStats.gunLength, viewmodelParams)

			if result then
				
				lerp(script:WaitForChild("viewmodelPushy"), CFrame.new(0,0,result.Distance),.25)
				aimrestriction = true

		else

				lerp(script:WaitForChild("viewmodelPushy"), CFrame.new(0,0,0), .25)
				aimrestriction = false

			end

		end
