Lighting Problems

[anonymous_user_9a5abe07]

hey Guys , I have this problems with lighting …
its far better when I test it in normal map lighting , but when I make it to run for Mobile it gets far worst . please take a look at the images below :

files are exported as ASE from 3dmax and they are made with boolean methods which I hear may cause problems , if someone knows the fastest way to fix it , we are kinda in a rush ,
thanks a lot .
