Intersting. I found out that if you don't use static ip's the names of the cows get mixed up in hypervue, so when you think you are rendering to cow a. it is really rendering to cow b. I also use different ports for both pcs 5002 & 5003. I only use 2 computers and the 1st pc has hypervue and a cow while the 2nd has a cow. I sometimes add a 3rd pc but anymore pcs always screws up the farm & lends itself to the inevitable reboot or reboots. I gave up and just rendered the scene with one pc. I wanted to compare different motion & render settings over the network but I'll just leave out the network variable. Thanks alot for your help.
