OK, I may be doing this all wrong! I have a mansions level made up of 5 rooms (first floor) and I have gone and made each room in a separate wmp file and made the lighting correct in each. I compiled each room and then loaded all the rooms in as map entities in a new level file. Now I compile and run this new level of entities and it looks very bright most of the time but if you turn in the right direction, it goes right. As soon as you leave that spot though, it goes bright again.

Is there a better way to have separate rooms go into one level? If so, am I doing or not doing something to make the combined level bright?

You see I am having each room farmed out to a different artist. Once they do their room, I want to bring them together on one level. The easiest way I saw to do it was to create each room as its own file and the artists could update their wmb file and the new room changes would reflect in the game running.

I think I may be trying the wrong thing.
