Thanks ockham, this will certainly be a time saver.
I've been using JesterCGI's flame in Poser 5 to create animations lit by tourches using two or three spot lights per flame. I use the height of the flame as key to increase or decrease the intensity of the light. I also rotate the lights right or left by small degrees with the direction the flame flickers. I set this up with a single tourch on a wall and it looked pretty good animated. It's much more difficult with 5 tourches in a corridor with somebody walking up it. So I end changing the lights a little then rendering the animation to see the effect then changing them again and again. It gets a little tedious, but once I get the hang of the technique it should look pretty good.
