John are you talking about directional lighting? Theres a slight problem with that, and that is... The direction where a light is cast won't stop at a wall, it'll continue beyond.
This is especially problematic for outdoor areas with houses - houses will have a light cast on their front outer wall for example, which is great, but the wall behind the front wall (the interior wall) will also have the light cast upon it.
For me, working with directional light was a pain for a number of reasons...
- Light does not cast any shadows
- Light size and shape cannot be changed, so light cannot be focused in an area direction, rather the direction set applies the light 'globally' to the map without any falloff
