Mobil Previewer and physics

[Alessaint]

Hi,

if I'm not mistaken the December UDK doesn't support Physx on iOS meaning that no rigid bodies can be simulated (KActors), right? In mobile previewer however the Kactors work just fine. Is this intended? Are there other things that work in previewer and not on the actual device? Or is the previewer meant to be used only to check materials, lighting etc?

Thanks
