Forget Batch Render and use Network Queue instead. You CAN do it
with ONE machine! Just edit the 3DSNET.SET file's first few values
(clearly marked), then load each Project one at a time and tell it to
Video Post Render as "Net Queue" to <Any> machine. Then, when you've
put the last one into the Queue, simply put your machine into Slave
mode and go home for the day! 🙂
