Quote - I've never seen concincing interior lighting of a room that HAD a ceiling in Vue, but that's just me.  :(

This is something I'm working on, but it's very hard. Often I need to do shots that will include some of the ceiling. It's not too difficult for rooms that are entirely artificially lit - the real difficulty is doing a bright room lit by sunlight coming in from the windows. The area directly lit from the windows needs to have sharp shadows, but the rest of the room must (a) not be dark, and (b) not be shadowless. The GI and radiosity models have not proved useful so far.

I have had some success by putting a very strong, very distant spotlight in the sky with shadows set to 50%. This is then only partly blocked by the ceiling. Oddly enough, this trick does not work with directional lights, and I don't know why.
