A group of programmers we met some time ago built this engine and wish for it to be implemented in Unity.
the vid there has nothing to do with mobiles I fear, already the particles shown part of the time are enough to kill a mobile on a good day without considering the soft realtime shadow which is more than mobiles can handle…
and unless its physx based it won’t work with unity (nor do I see anything else being implemented in unity, single platform solutions won’t be implemented anyway especially not when replacing crucial parts like physx which must work ± equivalent on any platform), but they can naturally still write a plugin to offer support for their engine, nothing stops them from doing so 
looks nice there and surely sweet for desktop games
Hes talking about a physics engine not a graphic engine. And yes its PhysX based.
