[Question] Toptiling and Underground Lighting?

[[R-DEV]~KILL~Pirate]

What are the standard Toptiling settings for PR maps? I curently have my Toptiling low set to 60 and Toptiling high is still set at default and not really sure what it should be set at..
I am also making Underground bunkers for caches and setting larger buildings over top with small outside entrances leading to bunker. With that being said, will you still be able to see in the bunker without any additional lighting needed. It seems I can see fine Underground in the editor, but wasnt sure about the iin-game lighting.
