I just recently set an image to render on my other machine, it was going to take 18 hours. When it finally finished I discovered that part of the image had a really wierd artifact around the volumeric materials I'd used. Rather than do it all again I did a plop and fixed it in PhotoShop. So from my heart dropping to the floor I managed to repair it, and whew thank goodness for that. I also turn the monitor off when it's one of those long renders otherwise I think I would commit harikari. 8) Catlin
