I am attempting to set up a scene that is outdoors at night with light (candlelight) shining through a window. What is the best way to achieve this? ~Blade~

Have you tried "UltimateFire" by Romance works? There is a freebie here of a candle flame that you can try out to see if you like it. If so, you can buy the the rest of the package here too. (: I really like it and would recommend it to Poser users...it just doesn't work too well in Vue.(:

I don't know about the freebie candle flame, perhaps that's the solution. Other wise you could just place a spotlight at the position of the candle and point it through the window, you may need to adjust the 'Angle Start' and Angle End'. Make sure the wall/window frame, and light are set to cast shadows. Probably add some opacity to the window. Perhaps use a transmaped square to fake a light beam. If you need the candle to radiate in all directions, and you are using Poser 4, you could try one of my omni lights in the free stuff.
