Lighting interior and exterior

I'm trying to set up an exterior, with it's own lights. And an interior with it's own lights. How do I do it so the two sets of lights don't affect each other?

Probably you can use the material "max number of lights" to use the n number of lights closer to your object, you can place the lights in your scene in a way that the external lights dont influence interior objects

Or you can use the Ogre engine support for manually controlling what lights affect what objects, the Ogre engine will ask you application about what lights use and you will provide the lights you want (create or define a property to mark them external or internal when exporting)
