Toads don't tessellate. Trust me, I've tried. So how to Crytek pull it off? It's top secret, sadly, but you can watch one tessellated toad jump off a log in the latest CryEngine 3 tech on Gamespot , which also shows some lovely lighting tech and some grand Crysis 3 environments, some of which starred in the recent Crysis 3 combat/stealth trailer . It's pretty impressive, but is it better than the Unreal Engine 4 tech demo that Epic released a couple of months back?
