for the information of my possible advisors…

  • I am using the unity 4.6.1 pro
  • I made some other game with this version and any of those works fine
  • I use a single directional light and all material are mobile\defuse

I don’t know whether I can make my question understandable…But asking help to get rid of this weird problem… :frowning:

Well, it’s not half of the screen, it’s the shadow. Something’s wrong with the shadow of the Android build.
