Here's a quick suggestion if you have Vue 6 or 7:

create a ceiling - a thin cube - and position it just below the real ceiling or where the real one would be. Then turn it into an area light, leaving the output at 50%.

Select the 'Black Back' atmosphere under 'basic', and edit it to remove all fog and haze. Under the 'effects' tab turn lens flares off for 'directional' and 'all other' lights.Put the 'sun' below ground level to make sure it's completely turned off. This atmosphere doesn't use any of that fancy GI, GR and AO stuff so it's quick to render.

This isn't your final thing, it's a start point. Add point lights, change the color and output of the 'ceiling', turn GI, GR and AO on and off to see what happens...
