I've made a simple script that should detect if a part is not inside of a Region3 but i've realized that if the part is not inside the Region3, it will not trigger the script. Does anyone know any solutions or workarounds to this problem?

local regionPart = game.Workspace.RegionPart
local pos1 = (regionPart.Position - regionPart.Size/2)
local pos2 = (regionPart.Position + regionPart.Size/2)
local region = Region3.new(pos1, pos2)
local Preview = script.Parent:WaitForChild("Preview")


while true do
	wait(1)
	local partsInRegion = workspace:FindPartsInRegion3WithWhiteList(region,{Preview},100)
	for i, part in pairs (partsInRegion) do
		if part ~= nil then
			print("Blueprint is in region")
		else
			print("Blueprint is not in region")
			Preview.Position = game.Workspace.DefaultCenter.Position
		end
	end
end
