It's really simple. (which is the only reason I'm qualified to talk about it!) The above shows the location of the two lights as well as the "stupid shader tricks" used to create the luminous drapery. The bulb on the floor serves to imitate the bounced light in the room. It's distance has be set to 20 with the fall off set to 100%. It also serves to create the diffused light on the bottom of the drapery. Without it, all you see is the illuminated folds from the spot light and the rest looks as if it is in shadow. Hope this helps. Mark www.markbremmer.com
