I'm going to a general update of OS on my render farm. I think the Dale B way, can be a patch to the problem; i've just test it and i've see that in most case it work: i start hypervue and add only the system with Vue, after it start render add the other (one to the time). Now i'm starting a new render to try with stills (jpg) to add in a movie with Quiktime6. Thanks to all. When the project is finish i publisj it on web site to have your impression. Bye xman P.S. If you have other suggestion... reply me. :)
