On the fresh installed MAX 8(9) machine(s), run the BB (Backburner)
Manager. Go through all the setup about subnet and timeouts, etc.
Once it has run normally, close it and try re-running the
VRaySpawner60.exe
In Short - just open the Manager and click < OK >.
so I uninstalled backburner on my render slave, took off previous versions of max, and reinstalled backburner. Then ran the manager as you suggested, then started the vraydummy file, and it worked!
But, I then go to my workstation, bring up a max file, click DR, type in the name of my slave and hit resolve successfully, then start the render. The vray message box shows that it sent to the slave, but the slave never joins in (and I increased the render detail/size so that it would have time to join in).
And after finished, it does tell me that "warning: render host unknown (192.168.0,4) is not responding.
