Sorry to double post, but I think this is allowed.
I just want to post the results of the stress test I did last night, on WORLD. It was mainly to test the light mapper. Heres a picture of the end result:
Now for the statistics, these are from the file I saved while doing it:

From what I see on the forums, many people wont reach 420 light mapped objects for various reasons. For some it may be that you only light map your level,then use shaders to improve the other objects, visually. For others it may be the fact that their system wont allow them to have scenes of 1,000,000 polygons.
