Reality Factory

I realize the title makes it really newbie sounding but I need some help. I am planning on using different "worlds" for a game I'm designing but I can't seem to figure out how to change the lighting configurations for each, which is to have a level that's pretty dark and only uses lighting...

You're close rgdyman, AttachAccessory is a High Level command found under the MISC category. Unfortunately I don't think I understand how to use it effectively, sorry.
