Mobile Lighting and Geometry Problem

Hey guys
we built a map in 3dsmax , with UV maping and all , and when we import it in UDK the result seems fine , but just when we hit build all , there comes some lighting problems .
yet it is not so bad … for PC its like this

but after we get Mobile preview its horrible .

please help us we have no Idea what should we do to fix it .

Hey impedram -

The Answehub is specifically for Unreal Engine 4 exclusively. You can ask Unreal Engine 3 or UDK questions, here.

Thank You
