Now up to version 3. Even more robust; although I recommend running it in "stand alone game" mode to play test it (that way it wont crash the UE4 editor if something does go wrong).
My fast machine slowed down when it had over 12,000 polys, but it didn't crash ... and with 6000 polys the update happened in a few seconds. Interested to hear how it goes on your system
