It looks awesome agiel. This lighting problem is in vue 4? Reason I ask is that I did an image in vue 3.1 that had 15 lights and the moon, and it rendered without too much worry. It took 8hrs to render on a PIII 600 coppermine with 384mb ram. When I first started the scene..it refused to go through the preview render..this took anything from 1hr to 1.45hrs in preview mode. I fixed it by defragging my hard drive and then did my preview render, and then the final render went through on personal high settings without a problem. You could try checking to see the amount of fragmentation your drive has. I hope this helps a little..I know it isn't directly related to vue 4, but it might be worth a shot. Good luck :)
