Short description of error
You can see the Blender Fail. Description of management in the Fail.
After adding lamps. working only one.
This is very important when creating a game.
If this does not solve, the blender will not in good standing_ with the game creators.
For example, the new candle on the wall to hang, there where the player wants.
This problem can be solved, if shut off Diffuse or Rename object, in playable game.
Because object not writable, and "use_diffuse = False" don't work. it is depressing.
thank you and sory for my english.
