Double posting... I apologize.
Here is a VERY quick lighting test in UDK. This was the first time I've messed around in UDK, and I can tell you I'm going to have SOOO much fun with the lighting setup for this scene (and really any future work done in UDK).
Still need some meshes in there (bugging me more now since I've seen the quick bake)... like the main platform, really needs some broken up tiles / floor in generl to help break everything up more.
Still designing some areas as well, but at least this is a good base for me to get started on some sculpting, I'm hoping it will be a fun process, going to be doing a lot of tileable sculpts (which I haven't done before) so should be a good learning experience.
Need to fix smoothing groups as well...
