hello

I do not understand everything when rendering with DR.  
if only the vray RT distribute rendering is running then nothing happens on the other machines, but if I activate the ditribute rendering on vray, then the other machines show 100% cpu usage.

do I have to activate both distribute checkboxes in RT and vray?  
and setup the same IP’s in both DR’s?

best regards

The DR for the standard V-Ray and for V-Ray RT are completely separate; they do not share settings or server programs. So if you want to use DR with V-Ray RT to have to set it up separately (e.g. enter the server IP addresses in the RT render servers dialog, and start the V-Ray RT render server program on the render slave machines).

It doesn’t seem to understand DNS. Why is there a server name and an ip address column?

Yes. I also miss the “resolve servers” button to check the servers…
