Dale, Thank you for taking the time to give such a careful reply. 3) Dale said: "Nope [I can't have two cows on one computer]. But both the Cows and VuePro are multiprocessor aware, so they would use multiple threads in the rendering. The way the HyperVue network render system works, the actual Vue application functions as the controller. It handles file transmission, scene set-up and frame specifics. When it is doing this, it can't render, so you need a Cow on the controller system. I haven't tried to run multiple Cows on one system, but i suspect things are coded so that only one can run within an OS environment at a time. I could be wrong, but I doubt it...." So, my two dual processor Macs can NOT process two different frames at the same time, but since VUE/Mover is multprocessor aware, they will be efficient (fast) at processing the one frame they are rendering at a given time. Is that accurate? I am glad to hear I can go cross-platform. I think I will leave one computer completely off farm production, for surfing, emailing, Posering, modeling etc. I guess one of the three would be the controller and also render as a cow, right, and the other two just be nice contented cows? I just realized I have a functioning Mac 7200 accellerated to G3, I wonder if I could get milk outta that old thing. So, if you had the following three computers on a farm, which one would you run as the master? Mac G5 Dual 1.8MHz 2.5/GIG/RAM 250GB/SATA/HD+80GB/HD Mac G4 Dual 400MHz 1/GIG/RAM 80GB/HD PC Athlon2800 1/GB/RAM 80GB/HD Again, thanks for your reply ::::: Opera :::::
