Hello all. I am making an indoor timelapse animation in XSI. This includes a Physical Sky/Sun, 4 portal shader area lights (one in each window of each wall of every side), and interior artificial lights for night. I would like to eventually throw in a moonlight but have not decidedyet. My animation is 600 frames (+-25sec.). Should I use FG with GI? Also wondering if I could use the append FG map. Would this give acceptable results considering the light sources are changing location and intensity?
