Well, the main issue I'm having with lighting is that CryEngine seems to force dynamic planet lighting, I suppose because the engine is usually used for outdoor natural stuff. For this, I don't necessarily want any external lighting to take effect. I want each individual light panel to provide the lights for each section.
Ah...I think that was one of the reasons I chose UDK over CryEngine3 when I upgraded. I hope you get that worked out, as I'd love to watch your progress on this!
