normally when a render is taking this long (yup, it's still going) i just hit cancel and adjust my settings to try and reduce the render time, but since i'm only just starting to play around with vue, i thought i'd see how much of a difference Global Illumination will make. with my luck, it'll look exactly the same as the non-GI version which takes 3-4 hours to render instead of 24hrs to get to 48% :p
