hello

I use various lights in my scene knowing that each light lights one object by the method of the layers. My problem, it is that when I export in exe from blender 2.25, I see that the lights do not light the object for which it had been created, but all the scene. Blow all the lights are combined and it is on enlightened... logic... there is probably an option to activate in order to keep this lighting by layer.
if you have an idea of this problem, it will be great of you to help me ...
thank you
