I have tried a simple 1024x768 100DPI Test render and it also bogs out. I am wondering if putting in three imported Poser characters is doing it. It is a pretty complex scene, the great hall of a Mage's guild. A lot o high res textures for walls and such, plus some very detailed candle chandeliers with a lot of small lighting sources for the individual candles. Maybe I need to go to 4GB RAM lol :) I'll keep trying. I really want to use indirect lighting to get the right effect from the light sources. I am probably going to have to remove a few of them to get this thing to render. I hate memory allocation errors...
