Dark Rooms

Uh, I made some rooms in my quest dark. Unfortunately, when the lights go out, you can still see the floor just fine, such that it is rather pointless to make the room dark. Anyone know why?
And the majority of the room uses cset 2 if this helps. Some parts use csets 3 and 4 though, and those parts darken correctly.

edit:
Never mind. It fixed itself. I couldn't for the life of me tell you why though.

I think that it has something to do with the quest rule "fade c-set 5". But other than that I've had problems with dark rooms on certain c-sets and not on others, and it baffles me, heck the tutorial makes it seem so easy, lol.

It's in the palettes. When you edit your level palettes, look at the black numbers. Any colors showing here will show in the dark rooms of that particular cset.

This is a silly problem in the newfirst gp too!
Thanx for the info with the black numbers!
