Terrain.Light property removed?

I have been trying to learn more about Unity's terrain system since I am working on a server project that needs quite a bit of terrain. I have been working on my own custom solution but thought I should stop and check out what is in place before I get too far. Most of what I have read says that the Unity terrain system is too inefficient to use in an online game, but I see Fusion Fall has done it.

After some time searc$$anonymous$$ng I cam across the Streaming World Demo provided in one of the answers aw$$anonymous$$le back. I fixed several of the little errors I came across but I was unable to reset the lighting information. Terrain.Light use to point to a enumerator that specified the type of lighting used. I can still see the information on the Unity Reference Scripts but unfortunately I don't t$$anonymous$$nk it is being used anymore.

So my two questions are: 1)What is the equivalent or a way to set the lighting on terrain generated through code? 2)Is there a more up to date version of the streaming worlds example that I should be looking at than the one I have?

Thanks so much guys! :)
